Abstract

In this research a novel interferometric system is reported, which allows the generation of four simultaneous interferograms with phase shifts, the system consists of three coupled interferometers: a Sagnac interferometer which generates an interference pattern with crossed circular polarizations, coupled to two Michelson interferometers which operate as a multiplexing system, generating replicas of the interference pattern. The optical phase is calculated using the well-known four-step algorithm. The results obtained for static transparent samples are presented.
