Abstract
A system and method to produce a hologram of a single plane of a three dimensional object includes an electromagnetic radiation assembly to elicit electromagnetic radiation from a single plane of said object, and an assembly to direct the elicited electromagnetic radiation toward a hologram-forming assembly. The hologram-forming assembly creates a hologram that is recorded by an image capture assembly and then further processed to create maximum resolution images free of an inherent holographic artifact.

A holographic method for detecting interference of electromagnetic waves emitted exclusively from a single previously isolated plane of a three dimensional object, the method comprising:
- receiving, at an optical arrangement including an objective lens, an optical relay system, and a polarization-sensitive optical element electromagnetic waves from the previously isolated plane of the three dimensional object;
- relaying a back pupil plane of the objective lens to a plane containing the polarization-sensitive optical element;
- for each point of a plurality of points in the said isolated single plane of the three dimensional object:
- forming, by use of the polarization-sensitive optical element in the optical arrangement, a first beam of electromagnetic waves and a second beam of electromagnetic waves from electromagnetic waves emitted exclusively from said each point;
- and
- detecting exclusively a pattern of interference between the first beam and the second beam;
- and
- reconstructing an image using the detected patterns corresponding to the said plurality of points in the said single plane.
A holographic system for detecting interference of electromagnetic waves emitted exclusively from an isolated single plane of a three dimensional object, the system comprising:
- an optical arrangement configured to:
- receive electromagnetic waves from the said isolated single plane of the three dimensional object using an objective lens;
- optically relay, without alterations of the light phase other than lateral field size, a back pupil plane of the objective lens to a plane containing a polarization sensitive optical element;
- for each point of a plurality of points in the single plane of the three dimensional object, use said polarization sensitive optical element to form a respective first beam of electromagnetic waves and a respective second beam of electromagnetic waves from electromagnetic waves emitted exclusively from said each point;
- and
- a detector configured to:
- for each point of the plurality of points in the single plane of the three dimensional object, detect exclusively a pattern of interference between the respective first beam and the respective second beam;
- and
- reconstruct an image using the detected patterns corresponding to the plurality of points in the isolated single plane.
