Abstract
A scanning optical rangefinder including an optical scanner and a light source. The optical scanner includes a rotating scan disc with a circular array of concave reflectors thereon. Mirrors are provided for directing light from the light source towards the concave reflectors on the rotating scan disc and then to direct light from the concave reflectors on the scan disc towards a target. Light received from the target is directed towards the concave reflectors on the scan disc by mirrors along a plurality of channels. A detector adapted to receive light reflected from the concave reflectors is provided for each channel, along with error correction for parallax data from the detector. The light is directed towards the target along a channel laterally displaced from a channel for light received from the target.
