Abstract

In order to achieve high-precision non-destructive evaluation of optical heterogeneity, we develop a parallel phase-shift digital holography system, which enables measurements of the optical path differences at a nanometer-scale resolution. The amplitude and phase distributions of the object wave can be reconstructed directly from a single hologram by using the parallel phase-shift digital holography system. The system can be applied to evaluate the glass plate samples and the glass with the shape of an axially symmetric converging lens. We perform the fundamental experiment to measure the phase profile of the object wave which passing though the optical flat and plano-convex lens in order to evaluate the optical homogeneity of the sample.
