A laser beam with a pseudo random bit stream pattern amplitude modulation is retro reflected off a target to produce a real time ranging signal using a cross correlation technique. The measured resolution of the system was 0.2 mm with an absolute acc

An optical sensors web in a star pattern is formed and tested utilizing modulating retro-reflectors, where a multitude of sensors was simulated by a retro-modulator on a mini-rover. A CCD camera provides the multi-mega-bit sensor signal. Two-dimensio

An electronic technique is described whereby the heterodyne mixing frequency of a pulsed LIDAR transmitter is displayed on a color‐coded linear bar graph. The technique is of great utility for manually fine tuning the laser output frequency when th
