摘要
A simple method for making a robust interferometer based in holographic optics is now available. The method is suitable for performing optical test studies on phase (transparent) objects. The advantage of the method lies in the fact that the optical arrangement of the interferometer involves a very simple alignment procedure and portions of anyone of the lower-half or upper-half of the collimated beam can be used as a test arm for studying the phase objects.
