Automated Visual Measured Inspection Modul

2D laser triangulation module with integrated microprocessor system

A 2D laser triangulation module with a built-in microprocessor ultrasonic inspection system allows you to measure the profile of an object with high accuracy without mechanical contact with it.


The laser module uses the principle of triangulation. The laser beam deployed in a perfect straight line is projected onto the surface of the inspection object. The light line repeats the shape of the profile of the object in the cross section. The image of the light line is projected onto a CMOS photo matrix. According to the coordinates of the image on the photodetector, the microprocessor calculates the real coordinates of the light line (profile). During the measurement process, the reflected light power is dynamically monitored and background illumination is suppressed.

To obtain a 3D-shape of the object's surface, the laser module is moved using a scanning device. The signals of the displacement sensor are used to synchronize the profile measurements.
