Holographic Optics Based Interferometer for Comparative Studies of Phase Objects

摘要

In this paper a versatile holographic optics based interferometer is presented in which two different phase type objects can be studied simultaneously and also the same interferometer can study a single object in two different modes at the same time. In this configuration simultaneous phase shifting in both the interferograms is also possible by moving a single inbuilt element. The optical configuration for the realization of proposed interferometer utilizes two holographic optics and one diffraction grating in conjunction with a collimating optics.
