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 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.

Software

The ProfileTrak™ G series is provided with a free SDK software and LabVIEW drivers. Each SDK comprises of the DLL for C# and C++.

A free demo program is also offered to get the 2D/ 3D sensor working instantly on a PC so the user can visualize a 2D profile or a 3D profile if encoder input is available. Moreover, the PTG series sensors can also function with a majority of GiGE client software such as Halcon, Matlab, NI LabVIEW etc.
