Classification: CPC G | IPC G

Claim 9:
10. 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.
