摘要:
A simple holographic interferometer for observing a phase object is presented. The optical system is constructed by a cascade-type coherent double diffraction system with two spatial filters. Since the object beam and the reference beam take a common path, the interferometer is proof against external vibrations. The interferometer is able to obtain not only an ordinary interferogram but also a phase contrast image or a differential interference contrast (DIC) image.
