Two dimensional range-imaging

摘要

A two-dimensional range-imaging system is capable of transmitting light from a source into a field of view and focusing return portions of the light, reflected off targets in the field of view, onto a two-dimensional array of photodetectors. The photodectectors convert the return portions of light into electric signals that are compatible with a solid state circuit. Each electric signal is combined with a one or more reference signals to indicate a distance between the source and an associated target.
