Digital micro-mirror holographic projection

A light interferogram projection device comprising:

• a coherent light beam-generating device;
• a beam splitter disposed to receive a first coherent light beam from the coherent light beam generating device and to emit a second coherent light beam and a third coherent light beam at differing angles;
• a processor programmed to receive an image or model and to generate a holographic transform from the image or model;
• a digital micro-mirror device connected to the processor in such manner as to display the generated holographic transform thereon and disposed to receive the second coherent light beam from the beam splitter;
• and
• an imaging plane disposed to simultaneously receive both the generated holographic transform from the digital micro-mirror device and the third coherent light beam from the beam splitter, and to combine the simultaneously received holographic transform and third coherent light beam into an interferogram projection comprising the image or model.

A method of creating a light interferogram projection comprising:

• generating a coherent light beam;
• splitting the first coherent light beam into a second coherent light beam and a third coherent light beam projecting at differing angles;
• disposing a pattern derived from an image or model on the surface of a digital micro-mirror device disposed to receive the second coherent light beam from the beam splitter, and generating a modulated light pattern;
• simultaneously receiving both the modulated light pattern and the third coherent light beam onto an imaging plane;
• and
• combining the simultaneously received modulated light pattern and third coherent light beam into an interferogram projection comprising the image or model.
