Transmissive/reflective optical scanning apparatus

摘要

An optical scanning apparatus for retrieving digital electronic images representative of opaque and transmissive objects. The apparatus is equipped with an optical switch which is operated by solenoid switches positioned at one end of the scanning apparatus. A scanning camera equipped with transmissive and reflective light sources for illuminating the corresponding objects may be selected by the operator to retrieve images of either the reflective or transmissive object type.
