Line Scanner Measurement Principles

The ProTrak™ G applied the triangulation principle to get a 2D height profile of target surfaces. A laser line generator projects a diverging line that has a starting dimension of beginning range x and maximum width dimension at end of range x. The line is diffusely reflected back onto the CMOS camera array via focusing lenses. Then the CMOS line profile image is processed using the internal electronics and an X-Z array output is produced for the application or display software at up to 4 kHz update rate. By moving the sensor along with the target the application software is able to construct a 3D image of the target. Encoder inputs enable synchronization of the motion with X-Z profile data.
