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 ste-reoscopy and holography. The optical principle and system of this miniprojector, recording scheme of holographic diffusing screen, improvement of chromatic dispersion of screen and characteristics of projection system are discussed.
