Abstract

To reduce keystone distortion in tilted imaging systems when the object area is much larger than the lens diameter, an optical system design using a digital micro-mirror device (DMD) is proposed. Keystone distortion is analyzed, establishing the relationships between keystone distortion and object height, tilt angle of the object plane, focal length, and object distance. A design with a DMD in a reimaging setup is analyzed, providing a solution that eliminates keystone distortion in tilted imaging systems. The method is validated by simulation and experiment; it provides an innovative method to correct keystone distortion without digital signal processing.
