The laser profilometer developed by POMEAS scans the three-dimensional profiles of different surfaces using the principle of laser triangulation. Laser beams are amplified by a set of special lenses to form a static laser line and projected onto the surface of the object under test. The high quality optical system projects the diffuse reflected light of the laser line onto the sensitive sensor matrix.
In addition to the distance information (Z axis) from the sensor to the object under test, the controller can also calculate the position along the laser line (x axis) through this set of images. The sensor eventually outputs a set of two-dimensional coordinate values. The origin of the coordinate system is relatively fixed with the sensor itself. By moving the measured object or sensor, the three-dimensional measurement results can be obtained. Laser Profile Sensor Solves Your Various Measurement Requirements.
1. Non-contact measurement
Laser profilometer is a typical non-contact measuring sensor, which uses the profiles generated by laser beam on the surface of the target to measure the three-dimensional profiles. It has the characteristics of no measuring force, no wear and long life, and can work in various workplaces for a long time.
2. High measurement accuracy
At present, the repetition accuracy of POMEAS laser profile sensor can reach 0.2um.
3. Fast measurement speed
At present, the maximum sampling frequency of laser profile sensor can reach tens of kHz.
4. Multiple Measurement Parameters
Laser profile sensor can measure many two-dimensional profile parameters, including height, height difference, position, centroid position, width, center distance, point-point distance, point-line distance, radius, angle, inclination, centroid position, cross-sectional area, standard profile deviation, etc. When combined with longitudinal displacement information, three-dimensional shape can be obtained. Information, powerful.
5. Wide scope of application
Because the laser profile sensor uses laser as the measuring medium to realize the accurate measurement of the two-dimensional profile parameters of the target, it has no too many restrictions on the target to be measured, including hard and soft, hot and cold, black and white, light and shade, etc. It is especially suitable for some soft targets (such as rubber, plastic, film, etc.) and narrow space (such as parts). Grooves, blind holes, IC pins, etc.
