Abstract
A scanning projector includes a MEMS device with a scanning mirror that sweeps a beam in two dimensions. Actuating circuits receive scan angle information and provide signal stimulus to the MEMS device to control the amount of mirror deflection on two axes. The scan angle information may be modified to maintain a constant image size, a constant image brightness, and/or to correct for keystone distortion.
