Method and apparatus for controllably compensating for distortions in a laser projection display

摘要

A method and apparatus are provided to controllably compensate for distortions in an image produced by an LPD, where the distortion arises from the shape and/or angle of the viewing surface relative to the LPD. For example, the LPD can determine the angle of the viewing surface relative to the LPD and then adjust the horizontal and vertical scan mechanisms to return the image to its original configuration, such as rectangular.
