RD-17,787 MULTIPLE CHANNEL OPTICAL FLYING SPOT TRIANGLATION RANGER SYSTEM Abstract of the Disclosure Multiple light detection channels are introduced into a flying spot optical triangulation ranging system to increase the speed of acquiring range valves. A laser beam is rapidly swept across a surface by a beam deflector. Each fiber optic channel can receive light only from a different point along a line at the inter- section of the swept beam with the surface. The receiver channels are duplicated and separate detectors generate signal pulses at times that are a function of range to the surface. These are processed in parallel to calculate N range values per beam sweep, where N is the number of channels.
