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.
