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.

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.
A method of setting a holographic interferometer, comprising:
- positioning an imaging device for capturing an interference pattern created by at least two polarized light beams;
- positioning a structured phase retardation element in an optical path of at least one polarized light beam of the at least two polarized light beams;
- and
- positioning a polarizer in front of the imaging device, so the polarizer projects the polarizations of the at least two polarized light beams on a single axis.
