Abstract
A diffracting beam splitter splits an optical beam. The resulting beams are swept over an object by a beam deflector. The beams are mechanically scanned transverse to the beam deflection direction. A position sensitive device receives light reflected from the incident beams and a three dimensional profile of the object is produced.
