Abstract: The present invention relates to a compact display projector and a method of using it to project images under the control of image generating equipment, such as computers and television systems. An optical input device (10) is built into the projector (12) to enable optical control signals directed onto the projected image, to be discriminated for causing the image generating equipment to modify the projected image. A positionally adjusted mirror device (40) is disposed in optical alignment with the optical input device to reflect the optical control signals back thereto, whereby the optical input device is readily aligned with the projected image to monitor it for the occurrence of any optical control signals.

Abstract: An image projection system includes a source of polarized light and a spatial light modulator, having an alignment layer, wherein the polarized light is aligned with the alignment layer to allow the light to pass without the need for polarizers. Three different colored images may be produced by three separate polarized light sources (222A, 226A, 230A) with corresponding light valve super-imposed. Light sources may either be maintained activated or may be sequenced at high input energies for short intervals to reduce average energy costs. A microlaser array (922) may be coupled with a beam shaper (936) to further increase brightness of the image. The beam shaper may include a binary phase plate to modify the shape and intensity profile of the projection light beam.
