Abstract

In this paper, a new interferometer is proposed and employed to investigate transparent object by means of LED(light emitting diode)-based digital holography. The interferometer combines the advantages of Mach-Zehder interferometer and Michelson interferometer, it enable us to adjust the optical path difference of the two beams interference on a Mach-Zehder interferometer. Thus the interference fringe patterns of LED could be observed quickly and conveniently. First the principle of the new interferometer is stated and then it is compared with other interferometers. Secondly, LED-based phase-shifting digital holography is carried out to investigate transparent object. Both theory and experiment results are presented.
