Abstract

A 3-D holographic miniprojector on the basis of holographic optical element screens using for integrated circuits assembly and quality control is described. This is a compact, professional projection-type microscope using hybrid technique combing the advantages of both stereoscopy and holography. The optical principle of this miniprojector, recording scheme of holographic diffusing screen, improvement of chromatic dispersion of screen and relative parameters of projection system are discussed.
