Abstract
A holographic interferometer, comprising: at least one imaging device capturing an interference pattern created by at least two light beams; and at least one aperture located in an optical path of at least one light beam of the at least two light beams; wherein the at least one aperture is located away from an axis of the at least one light beam, thus transmitting a subset of the at least one light beam collected at an angle range.
Claims14
A holographic interferometer having no reference mirror, comprising:
- at least one imaging device capturing an interference pattern created by at least two light beams collected from an illuminated subject structure;
- and
- at least two apertures, each located along an optical path of one light beam of said at least two light beams;
- wherein said at least two apertures are each differently located away from an optical axis of a respective one of said at least two light beams, thus transmitting a substantially different subset of said at least two light beams of different collected angles range having different effective wave number;
- and
- wherein each of said at least two light beams is arriving into said at least one imaging device at a different angle with respect to said at least one imaging device, to create said interference pattern.

A method of setting a holographic interferometer having no reference mirror, comprising:
- positioning at least one imaging device for capturing an interference pattern created by at least two light beams collected from an illuminated subject structure;
- and
- positioning at least two apertures, each along an optical path of one light beam of said at least two light beams;
- wherein said at least two apertures are each differently located away from an optical axis of a respective one of said at least two light beams, thus transmitting a substantially different subset of said respective one of said at least two light beams, each said subset includes light collected at different angles having different effective wave number;
- and
- wherein said each of said at least two light beams interferes on said at least one imaging device at a different angle.

- and
- at least one imaging device capturing an interference pattern created by said at least two light beams after reflection from an object;
- wherein said at least two light beams have different angle of incident on said object corresponding to different effective wave number.
