ABSTRACT:
A deformable mirror system for reduction of projected image distortion in an optical system is disclosed. The mirror is adapted to correct for ray direction. In accordance with the invention, a mirror is located near an intermediate image plane. The distortion in the image is predetermined, and the mirror is contorted in a manner determined by the distortion to be corrected; relationships are prescribed for the desired contortion. Significant reduction in distortion can be achieved by placement of a mirror near the image plane; furthere reduction can be achieved in accordance with the invention by the placement of an additional contorted mirror at a subsequent image-forming aperture in the optical system.
