摘要:
A projector for projecting diffracted light in a selectable pattern and/or animation on a display surface. The apparatus includes a light source providing one or more beams of coherent light from one or more lasers. The apparatus includes a diffraction assembly in the path of the light source to generate diffracted light by diffracting the laser light with one, two, or more diffraction grating patterns and, optionally, with a diffraction glass or other material. An active mask is provided with a raster that receives the diffracted light and that includes a plurality of optical shutter elements that are selectively operable to project a portion of the diffracted light from the active mask toward the display surface. In one example, the active mask includes a liquid crystal display panel to provide a grid of addressable programmable pixels that are turned on and off to project portions of the diffracted light.
