Triangulation Measurement System

The LK CCD Laser Displacement Meter uses a triangulation measurement principle as follows: A semiconductor laser beam is reflected off the target surface and passes through a custom designed receiver lens system. The beam is focused on a CCD sensing array. The CCD detects the peak value of the light quantity distribution of the beam spot. The CCD pixels (individual CCD sensing elements) within the area of the beam spot are used to determine the precise target position. As illustrated in the diagram above, as the target displacement changes relative to the LK sensor head, the reflected beam position changes on the CCD array. These positional changes are analyzed by the LK Controller which resolves height changes as small as 10 microns. (LK-503 High Precision Mode)
