| 摘要 |
The present invention relates to a method and apparatus for display of three-dimensional images and production of mega-channel phase-encoded optical communications. In certain embodiments, the device of the present invention allows for the creation and display of real-time, three-dimensional moving holograms. In the present invention, a computed image or virtual model of a real object is stored (18) in a computer or dedicated digital signal processor (DSP) (12). The stored image or model is then converted by the computer or DSP into its Fourier, or holographic, transform. The holographic transform is displayed on a light modulation device (16) that is illuminated by a one portion (20) of a laser emission (22). The remaining portion (26) of the same laser emission (22) is combined with the holographic transform at a plane (28) to create a three-dimensional image (38).
