![]() National Research Council Canada - National Science Library The random pixel addressability allows concentration of scanning and processing on the active areas of a scene, as is done by the human eye-brain systemģ- D Imaging by Laser Radar and Applications in Preventing and Combating Crime and Terrorism The system maintains the immunity to lighting and surface shading conditions which is characteristic of coherent laser radar. The approach includes a compact scanner with no moving parts capable of randomly addressing all pixels. Recent advances in fiber optic component technology and digital processing components have enabled the development of a new 3 D vision system based upon a fiber optic FMCW coherent laser radar. International Nuclear Information System (INIS) Camera.įiber optic coherent laser radar 3 d vision system We use a high sensitivity, fast, intensified CCD camera, and a Nd:Yag passively Q-switched 32.4 kHz pulsed green laser at 532 nm. We have developed a mono-static staring 3- D laser radar based on gated viewing with range accuracy below 1 m at 10 m and 1 cm at 100.
