Abstract
Briefly, in accordance with one or more embodiments, scanned beam projector may comprise a light source, a scan drive and a scanning platform to project an image onto a projection surface. The scan drive circuit is capable of at least partially correcting distortion in the projected image by varying an amplitude of the scan drive signal to at least partially compensate for the distortion in the projected image.
