Abstract
A holographic interferometer, comprising: an imaging device capturing an interference pattern created by at least two polarized light beams; a structured phase retardation element located in an optical path of at least one polarized light beam of the at least two polarized light beams; and a polarizer located between the imaging device and the structured phase retardation element, the polarizer projects each polarization of each of the at least two polarized light beams on a single axis to create the interference pattern on the imaging device.
