Abstract
A system for generating three dimensional images includes a data processor which generates a first data stream representing coordinates along a first axis, a second data stream representing coordinates along a second axis, and a third data stream representing intensities of optical beams. A demultiplexer transforms the first, second, and third data streams into multiple control signals each comprised of elements of the first, second and third data streams. The system further includes an optical energy source for generating an optical signal, and an optical beam steering system which divides the optical signal into multiple optical beams which are individually deflected and intensity modulated under the control of one of the control signals. The optical beams then are recombined and steered to reflect off the reflecting surface of a reflective structure, resulting in the presentation of a 3D image.
