Abstract
In one embodiment, a color holographic image is created by generating a separate complex hologram for each of multiple different colors of an object field illuminated with incoherent light, combining the separate complex holograms to obtain a color complex hologram, and generating a reconstructed color holographic image of the object field.
Claims11
A method for generating a color holographic image, the method comprising:
- (a) using an interferometer to generate an interferogram of an object field illuminated with incoherent light for each of multiple colors, the interferometer comprising first and second mirrors that reflect light from the object field, wherein the mirrors have different radii of curvature;
- (b) displacing the first mirror along an optical axis of the interferometer to perform phase shifting;
- (c) sequentially repeating steps (a) and (b) until multiple phase-shifted interferograms are generated for each color;
- (d) combining like-colored phase-shifted inteferograms to generate a separate complex hologram for each color;
- (e) combining the separate complex holograms to obtain a color complex hologram;
- and
- (f) generating a reconstructed color holographic image of the object field.

A system for generating color holographic images, the system comprising:
- an optical system that collects incoherent light from an object field;
- an interferometer that receives the light collected by the optical system, the interferometer including a first mirror, a second mirror, a beam splitter configured to send copies of the received light to each of the mirrors, wherein the mirrors have different radii of curvature;
- a color light sensor that receives light waves reflected by each of the mirrors of the interferometer and generates separate interferograms each of multiple different colors from the interfering light waves;
- and
- a computing system that executes a digital holography system configured to receive the interferograms from the inteferometer and generate color holographic images of the object field based upon the interferograms.
