Paper Abstract

A new holographic system for measuring 3D amplitude field of the opaque object is proposed. This system has the single reference beam and the three object beams of spatial distribution, and the three overlapping time- average holograms used for analyzing amplitude are recorded on the same plate with the help of the rotation unit of the plate. The related analytical formulas are derived in accordance with the property of the surface shape of the measured object and the optical system designed. Experimental results are given.
