The gap distance shown in the diagram attached to reply #4 cannot be determined by one shot of any type of laser distance sensor.You get only one distance measurement per shot. So, make more than one measurement, scanning across the object field. The Lidar Lite should work well.
yeah i know that, but my idea is to build Laser 3D scanner like system with Laser Triangulation Principle. With this i can get all the data to do stuffs. But the thing is now im stuck at how to detect the LINE laser either with CMOS and CCD sensors.
