    摘要： A system for alternately directing optical energy through multiple optical modulation channels includes an optical switch having first and second optical output ports for alternately directing an optical signal at full input power out of first and second optical output ports; a first optical modulation channel for modulating the output signal received from the first optical output port; and a second optical modulation channel for modulating the output signal received from the second output port. The optical switch includes a Pockels cell and a birefringent mirror. The Pockels cell transforms a first polarization state of the optical signal into a second polarization state in response to receiving an input signal. The birefringent mirror allows the optical signal to propagate along a first axis when the optical signal has a first polarization state, and directs the optical signal along a second axis when the optical signal has a second polarization state.

    摘要： A sequential color scanner capable of generating both two and three dimensional moving color images has only one x- and y-deflection channel. The system includes first, second, and third optical signal generators for generating a first, second, and third optical signal, respectively. Each optical signal is characterized one of the three primary colors. The first, second, and third light signals are blue, green, and red, although not necessarily in that order. The first optical signal is generated along an optical axis. First and second beam combiners direct the second and third optical signals, respectively, along the optical axis. A first optical deflector deflects the optical signals in a first plane, and a second optical deflector for deflecting the optical signals in a second plane that is orthogonal to the first plane. First, second, and third modulators modulate the intensity of the first, second, and third optical signals, respectfully. A controller supervises each of the first, second, and third modulators so that the optical signals are generated in a pulsed, repeating sequence in accordance with an index that is counted by an index counter implemented in a controller. The controller also supervises modulation of the first and second optical deflectors so that the light signals are directed to predetermined coordinates. A time delay &tgr; is introduced between optical signals for enhancing the sharpness of the image by assuring that the optical deflectors modulate only one light signal at a time.

    摘要： 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.
