AN OPTICAL DETECTION METHOD FOR SEPARATING SURFACE AND DEEPNESS

摘要

An optical detection method is provided for non-contact measuring an object and separating surface and deepness information of the medium in the object. A light beam that irradiates the object from an incident unit is received by a receiving unit and detected by a detector. The separation of surface and deepness information of the medium can be achieved by a measuring system, and optical probers don't contact the object. In the present invention, the incident unit and receiving unit can be configured according to polarization method, optical baffle method, space imaging method, and Brewster angle method etc.
