摘要： A three-dimensional television camera system based on a spatial depth signal and receiver system therefor is disclosed wherein a video depth signal is generated in spatial synchronization with the raster scan of a TV camera viewing a scene. The video depth signal is generated by taking the ratio of the outputs of a pair of spaced apart sensors receiving a reflected laser beam of a laser projector situated between the sensors. The laser projector, sensors, and TV camera are in close proximity to each other. A portion of the energy receiving photocell of each sensor is blocked by a parallax barrier so that a proportion of the reflected laser beam energy is detected and that receipt of energy is angle dependent. By such construction, the depth difference of two points proximate each other is sensed. A continuous video depth signal is outputted in synchrony with the TV camera video signal to the receiver system. The described receiver system employs two TV cathode ray tubes to be viewed stereoscopically, i.e., one for each eye. On CRT operates as in a convention television receiver receiving the TV camera video signal and the other CRT receives the same video signal except the horizontal sweep component is modified by the video depth signal. By such instrumentality, a scene is viewed in three dimensions much like the sell known stereoscope.
