Abstract
A holographic, optics-based dual-channel interferometer with an in-built phase-shifting element is described. The interferometer can be used for testing two different phase objects simultaneously and independently. Additionally, a single object could be studied simultaneously in two different modes (e.g. finite and
infinite fringe states) in this interferometer. The related geometry of the proposed interferometer along with
experimental results is presented
