OPTICAL DISTANCE MEASUREMENT DEVICE AND METHOD THEREOF

摘要

A system and method of efficiently obtaining distance measurements of a target. A modulated optical beam may be used ot determine the distance ot the target. A first beam splitter may be used to split the optical beam and a second beam splitter may be used to recombine a reference beam with a return ranging beam. An optical mixing detector may be used in a receiver to efficiently detect distance measurement information.
