Abstract: A scanned light display system includes a light emitter array having a plurality of light sources operable to emit diverging light and an array of collimating elements positioned so that each of the collimating elements receive at least a portion of the light emitted from a corresponding one of the light sources. Each of collimating elements is configured to substantially collimate the received light from at least one corresponding light source into respective beams. The scanned beam display is operable to scan the respective beams to provide an image to a viewer. The displayed image appears substantially fixed to a viewer as the viewer's eye moves relative to the array of collimating elements. In one embodiment, each of the collimating elements is a curved mirror. In other embodiments, each of the collimating elements includes at least one lens or a curved mirror/lens pair.

Abstract: A control system for a projection display includes means for compensating for spatial variations or artifacts in light scattered by a projection screen. According to embodiments, a sensor produces a signal corresponding to the amount of light scattered to a viewer on a region-by-region or pixel-by-pixel basis. A screen map is created from the sensor signal. Input display data is convolved with the screen map to produce a compensated display signal. The compensated display signal drives a projection display engine. The projected light driven by the compensated display signal convolves with the display screen to produce a viewable image having reduced artifacts. According to one embodiment, a relatively fixed screen map is produced during a calibration routine. According to another embodiment the screen map is updated dynamically during a display session.

Abstract: A variable illuminator, for instance a device for scanning a beam of light, emits a selected amount of power to a plurality of spots across a field of view. The amount of power is determined as inversely proportional to the apparent brightness of each spot. In the case where the spot size is equal to pixel size, the device may operate with a non-imaging detector. In the case where pixel size substantially equals spot size, the output of the variable illuminator may be converged to produce a substantially uniform detector response and the image information is determined as the inverse of a frame buffer used to drive the variable illuminator. The illuminator and detector may be driven synchronously. In the case where an imaging detector is used, the variable illumination may be used to compress the dynamic range of the field of view to substantially within the dynamic range of the imaging detector.
