ABSTRACT:
A beam scanner is operable to scan light in two or more axes, typically in a raster pattern that includes a fast scan axis and a slow scan axis. Plural beams of light are scanned, each beam of light producing a scanned region that at least partially overlaps at least one adjoining scanned region. Scanned regions may be aligned to adjoin and overlap along a dimension corresponding to the slow scan axis. The beam scanner may comprise a scanned beam display and/or a scanned beam image capture device. In a display, the power level of overlapping displayed pixels may be scaled to provide smooth transitions between adjoining regions to improve the image quality presented to a viewer. In an image capture device, one or more detectors is operable to collect light scattered from adjoining regions and a controller is operable to produce an image from the scanned regions.
