Zero contact measurement technology with Laser

by ghisellerousso

For fast and precise optical measurements of displacement, ranges, locations, and profiles, laser measuring devices are used. High resolution is available in laser position sensors. They function without contact and are appropriate for demanding situations. The laser sensors are used to measure positions, dimensions, and surfaces in addition to figuring out fill levels. They have a measurement range of 2 to 2500 mm. Moreover, these sensors serve as the foundation for Laser Measuring System that is specially made to meet your needs.

Laser Measurement Technology in Food Industry 

This device is made to measure geometrical parameters without physical contact with tiny things like sunflower seeds. Each unique object is scanned by the 3D laser scanner which then determines its geometry. You can have both the parameters for each individual sunflower seed and the overall quantity too.

Laser Measuring System in framing 3D computer models

Any type of CNC machine can be equipped with this 3D laser scanning kit. It enables you to scan products and turn them into 3D computer simulations. The CNC system moves the sensor across the prototype line by line when in scanning mode. The XYZ coordinates array that results from this is utilized to build a digital model of the prototype.

Laser Measuring System for Pipes Dimension

For the contact-free measuring of geometrical characteristics like the diameter, roundness, or curvature of large-diameter pipes, an optical measurement device has been introduced. Its technical features can be modified for different tasks. The system operates under the concept of 3D laser scanning of things, followed by the creation of a 3D computer model and the identification of the geometrical parameters.

Measuring Surface Roughness

The surface roughness is determined by its irregularities. Visual impressions, tactile experience, and a numerical scale can all be used to evaluate surface roughness. A surface smoothness, sheen, as well as matte and textured, or mirror-finish, characteristics are frequently used to describe it. The imperfections present on an object’s surface cause these variations in look and tactile sensation. The geometrical properties of a surface are measured using a variety of mechanical and optical techniques. Surface irregularities on items are either purposely produced or as a result of a variety of circumstances, including vibration from cutting instruments and the material’s physical characteristics.

Surface roughness is a measurement of the slight variations in height of any physical surface. This differs from larger-scale variations like shape and waviness, which are frequently a feature of the surface’s geometry. Both quantitative and qualitative sides are looked at in the Surface Roughness Measurement Methods. From straightforward two-dimensional profilometry to more complex three-dimensional area analysis, quantitative analysis has advanced and now readily yields information about the surface structure.

Measurements of areal roughness using laser scanning

The degree of surface roughness is assessed using areal roughness measurement (areal method type) over an arbitrary rectangular range. Surface condition is more accurately represented by areal roughness measurement, which uses a greater sampling area of the surface. Areal roughness measurements are frequently carried out using a laser scanner. Areal roughness measurements are frequently carried out using a laser scanner. 

The other popular non-contact technique uses light. Without touching the material, a laser confocal microscope, focus detection system, or interferometer emits light that is reflected and read. These devices may measure soft or viscous materials and cause no damage to the sample because they are noncontact. Laser confocal microscopy makes it simple to do noncontact 3D observations and measurements of surface characteristics at nanoscopic resolutions. When examining and testing the surfaces of mating metals, measurements of this kind are crucial, particularly in the fields of aerospace, satellite design, vehicle manufacturing, and the manufacture of military equipment.
