Abstract
A three-dimensional (3D) display system includes a reference spatial light modulator configured to generate a reference wavefront. The system also includes an object spatial light modulator configured to generate an object wavefront. The system further includes a Hogel basis display positioned between the reference spatial light modulator and the object spatial light modulator. The Hogel basis display is configured to receive the reference wavefront and the object wavefront. The Hogel basis display is also configured to generate a light field based at least in part on interference between the reference spatial light modulator and the object spatial light modulator.
Claims20
A three-dimensional (3D) display system comprising:
- a reference spatial light modulator configured to generate a reference wavefront;
- an object spatial light modulator configured to generate an object wavefront;
- and
- a Hogel basis display positioned between the reference spatial light modulator and the object spatial light modulator, wherein the Hogel basis display is configured to receive the reference wavefront and the object wavefront, and wherein the Hogel basis display is configured to generate a light field based at least in part on interference between the reference spatial light modulator and the object spatial light modulator.
A method of displaying 3D objects, the method comprising:
- generating, by a reference spatial light modulator, a reference wavefront;
- generating, by an object spatial light modulator, an object wavefront;
- and
- receiving, by a Hogel basis display positioned between the reference spatial light modulator and the object spatial light modulator, the reference wavefront and the object wavefront;
- and
- generating, by the Hogel basis display, a light field based at least in part on interference between the reference spatial light modulator and the object spatial light modulator.
