Frequently asked questions

about contactless measurement

It refers to a dimensional measurement method that does not require direct physical contact with the object being measured. It uses special sensors and instruments to obtain accurate data without disturbing the object.

NCMs offer a number of advantages, including high accuracy, the ability to measure fragile or sensitive objects, ease of use and the ability to measure at a distance without disturbing the object.

The measuring instruments used for NCM include sensors, probes, infrared thermometers, scanners, profile projectors, thermal cameras, displacement sensors, spectrometers, scales and interferometers.

Non-contact measurements are widely used in many fields, including industry, metrology, aeronautics, the automotive industry, scientific research, medicine, architecture and the environment.

Non-contact sensors use different technologies such as infrared, laser triangulation, optical measurement and magnetic induction to detect and measure variables such as temperature, distance, position and humidity, without touching the object.

NCM is important for optical measurement because of its ability to preserve object integrity, provide fast, accurate and non-invasive measurements, and adapt to complex surfaces.

They can be highly accurate, depending on the instruments used and the measurement method. Some instruments are capable of measuring to within a few microns.

It offers a number of advantages over traditional measurement methods, such as greater accuracy, fewer errors due to physical contact, the ability to measure objects that are difficult to access, and faster measurements.

The 2 are closely linked in the field of vision engineering. Non-contact measurement uses optical techniques to capture and analyse the dimensions of objects, while machine vision uses cameras and software to inspect, measure and control parts and manufacturing processes.

Choosing the right instrument depends on the specific needs of your application. It is important to consider the variables to be measured, the measurement range, the accuracy required and the instrument's specific features.

Although they offer many advantages, they can also have certain limitations. For example, some surfaces may not be suitable, and environmental interference may affect measurements. It is important to understand the limitations of each measurement method.

Factors influencing its quality include sensor resolution, calibration accuracy, adequate lighting, system stability, the nature of the surface being measured and bandwidth for real-time measurements.

The profile projector can be considered as a type of measuring device used to carry out non-contact measurements. It uses optical principles to project the image of an object onto a screen or profile sensor. The profile sensor is an essential component of the profile projector, responsible for capturing information about the surface of the object.

The profile projector enables dimensional and geometric measurements to be made with a high degree of accuracy without having to come into physical contact with the object being measured. It uses a beam of light to project an enlarged image of the object onto a screen, where the object's contours and features can be observed and measured. Profile sensors record this information and transform it into usable digital data.

By combining the profile projector with a profile sensor, it is possible to measure dimensions, angles, shapes and other features without directly touching the object. This non-contact measurement method is commonly used in metrology, manufacturing and quality control, where accurate and repeatable measurements are required.

The profile projector and profile sensor are key components of non-contact measuring equipment, enabling dimensional and geometric data to be obtained with high precision, while preserving the integrity of the object being measured.

Deformation measurement is a technique used to evaluate changes in the shape or size of an object when it is subjected to external forces, stresses or loads. It is used to quantify variations in the size or shape of a material or structure under the effect of mechanical stress.

Various techniques and instruments can be used to measure deformation. Among them, visio machines (or vision machines) and displacement sensors play an important role.

Machine vision systems use cameras and image processing algorithms to capture and analyse the deformations of an object. They can accurately measure variations in the shape or size of a part by analysing the images obtained.

1.

 Product quality control: Your lightbox can be used to capture high-resolution images of products manufactured in-house. This enables you to carry out precise visual checks and detect defects, imperfections or variations in quality.

2.

Documentation and archiving: Photos taken in your lightbox can be used to document and archive manufactured products. They provide a visual reference for tracking production progress, comparing different product versions and providing evidence in the event of disputes or customer complaints.

3.

6.

Internal and external communication: The images captured in your lightbox can be used for internal communication within the company, for example to present products at meetings, training sessions or in reports. They can also be used to communicate with customers, partners and suppliers, providing clear, professional visuals of products.

There are various types of non-contact measuring machine used in different fields and applications. Here are some of the most common types:

1.

 Vision measuring machines: These machines use high-resolution cameras to capture images of the objects to be measured. They are often equipped with image analysis software to extract information such as dimensions, contours and surface defects.

2.

Laser scanning measuring machine: These measuring machines use a laser beam to scan the surface of an object and measure its topography in 3D. They provide precise data on the shape, dimensions and defects of the object.

3.

Optical scanning measuring machines: These machines use a technology that projects patterns or fringes of light onto the object to be measured. By analysing the deformations of the projected patterns, they reconstruct the 3D geometry of the object.

4.

Interferometric measuring machine: This type of measuring device uses the principle of optical interference to accurately measure variations in the height or distance of a surface. It is often used for applications requiring high accuracy, such as measuring roughness or thickness.

5.

Tomography measuring machine: These machines use tomography techniques, such as optical coherence tomography (OCT), to create cross-sectional images of the inside of an object. They are commonly used in the medical field, particularly for ocular imaging.

6.

Ultrasonic measuring machine: These machines use ultrasonic waves to measure dimensions, thicknesses and defects in materials. They are often used in industry for non-destructive testing of parts.

7.

Infrared thermography measuring machine: These machines use thermal cameras to measure variations in the temperature of an object. They are useful for detecting hot spots, heating faults and insulation problems.

8.

Profilometry measuring machine: These machines use optical sensors to measure the surface profiles of an object. They can measure roughness, dimensions and contours with great precision.

Photographic non-contact measurement solutions use optical measurement principles to assess the dimensions of parts. Here are some of the types of measuring equipment commonly used in these solutions:

1.

Machine vision systems: These devices use cameras and image processing software to capture and analyse the dimensions of parts. The images are processed to extract information such as object lengths, angles and contours.

2.

3D scanners: These devices create accurate three-dimensional models of parts by capturing clouds of points from multiple viewing angles. Processing software then converts these point clouds into 3D models, which can be accurately measured.

3.

Optical profilometers: These devices use structured light projection techniques to measure the profiles and dimensions of part surfaces. They project a series of fringes or patterns onto the surface of the part, then analyse the deformations of these patterns to deduce the dimensions.

4.

Interferometers: These instruments measure variations in the wavelength of light reflected or transmitted by a surface. They are capable of detecting extremely precise variations in dimensions, particularly in applications requiring high precision, such as optics or the semiconductor and electronic component industries.

5.

 Photogrammetry systems: These use triangulation techniques, analysing images captured from several cameras to reconstruct the 3D geometry of parts. These systems are particularly useful for measuring large parts or moving objects.

To ensure consistent quality is achieved when manufacturing many different devices or components, the results of the production process need to be checked regularly by taking measurements. These checks are performed in various ways: either outside of the ongoing process, by regularly removing individual devices and checking them using appropriate mechanical or optical measuring instruments; or via measuring stations integrated into the process, which are equipped with mechanical sampling systems or other non-destructive measuring instruments. Optical measurement sensors are ideal for integration into the manufacturing process..

Their ability to measure precisely, quickly and without contact, plus the option to integrate the results of these measurements into the production process directly, leads to increased productivity. This results in faster production processes at a consistently high quality, without the need to make mechanical contact with the object or damage it in any way. Optical sensors provide extremely accurate results even when measuring very small objects.

Various technologies are used to create precise optical measurement sensors with the most popular being:

Laser Triangulation Principle

Laser triangulation is a single- or multi-dimensional distance measurement resulting from an angular calculation. The sensor projects a laser light onto the measuring object. The beam reflected there is then mapped, via optics, to a particular place on a position-sensitive receiver element, depending on the distances involved. The distance to the measuring object is determined by triangulating the light source, the measuring point on the object, and the image of the light on the receiver element. Sensors are available with light spots of different sizes. It is better to use small light spot geometries for very small objects, whereas a sensor with a larger light spot is recommended for rough surfaces.

The same principle of operation also applies to sensors which use not a light spot, but a laser line, combined with a CMOS matrix receiver. In this case, a profile can be detected and evaluated directly, without having to move the object.

Chromatic-Confocal and Interferometric Measurement Principle

Chromatic-confocal measurement sensors use white light sources, whose light spectrum is directed to the measurement head via optical fibers. The OC Sharp displacement measurement sensor from SICK allows the user to choose from two different measuring methods.

The lens system integrated in the measurement head has been designed such that the individual wavelengths are all assigned to a different distance. OC Sharp makes use of chromatic aberration, which is usually an unwanted effect. Each wavelength is focused at a different distance, reflected by the surface, and the reflected wavelength is then evaluated in a spectrometer. The wavelength determined is assigned to a distance value in turn.

As with many sensors which operate according to the laser triangulation principle, several reflected wavelengths can be evaluated in this case too, thus enabling a relative material thickness to be determined for single- or even multi-layered transparent objects.

Interferometric Measuring Method

The interferometric measuring method uses the physical effect of interference on thin layers. We are familiar with this effect from puddles that shimmer with color, caused by a thin film of oil, or from soap bubbles, for example. Different wavelengths of the light are either weakened or strengthened by specific material thicknesses. A quick Fourier transformation is then used to evaluate the spectrum of the detected layers. Unlike with the chromatic-confocal measuring method, here it is not possible to evaluate an absolute distance, but just the thicknesses present in a system of layers.

Significant advantages over the laser triangulation principle are exhibited including:

&#; Larger tilt angles are usually permitted
&#; If the light path is partially shaded, a measurement result will still be obtained
&#; Light spot diameters of 4 µm enable very small areas to be measured or even allow measurements to be taken inside holes
&#; Even smaller layer thicknesses of transparent materials can be determined (over approximately 3 µm)
&#; The measurement principle for taking measurements of surface roughness has been described in a standard (DIN EN ISO , Part 602)
&#; The measurement head is a purely passive device and contains no electrical components

Challenges

There are many reasons to use optical measuring instruments:

&#; As a replacement for mechanical measuring instruments, which are subject to wear and therefore have to be replaced on a regular basis
&#; If damage to the final product, e.g., films or soft surfaces, caused by mechanical measuring instruments is to be avoided
&#; If the properties of the material to be measured do not generally allow for a mechanical measurement to be taken, e.g., media which are liquid, not yet hardened or basically soft, whose dimensions would change either reversibly or irreversibly if subjected to pressure
&#; If the surface to be measured cannot be accessed by mechanical measuring instruments, or can only be accessed with difficulty

When changing over to optical measuring instruments, a challenge which sometimes has to be met is how to achieve results that are comparable with those previously obtained by mechanical means.

Due to the different ways in which optical and mechanical measuring instruments work, the following must be taken into consideration:

&#; Is it even possible to measure the object or will the results by significantly influenced by physical factors, e.g., by semitransparent surfaces or multiple thin layers?
&#; How are deposits (e.g., oil, dust, chips, and so on) on the surface dealt with? Are filter mechanisms required, which do not apply
any defined pressure to the surface, unlike with mechanical measuring instruments?
&#; Since the measuring point for mechanical measuring instruments is usually much larger than that for optical measuring instruments, the measurement results obtained from the latter must be determined over a larger surface

The process of changing over from a mechanical to an optical measuring instrument can be quite costly and laborious; however, this must be balanced against the long-term benefits such as cost savings, increased throughput, no mechanical impact on the measuring object, and improved quality in every process step.
