Laser triangulation sensors operate with a laser diode that projects a visible light spot onto the surface of the target. The light reflected from the spot is imaged by an optical receiving system (usually a CCD receiver) onto a position-sensitive element. If the light spot changes its position, this change is imaged on the receiving element and evaluated.
At Tipteh, we represent the German manufacturers of laser triangulation sensors Micro Epsilon and Leuze electronic. Both manufacturers are considered to produce the best devices in their class.
