Claim 0:
1. 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.
