Abstract
PRS0847A foveated imaging system using a relatively simple optical imaging system with a reflective spatial light modulator at or near a pupil plane to correct off-axis aberrations. Maximum resolution is obtained for a single fixation point (foveal region) within the field of view at a time. The fixation point can be changed manually, by a predetermined scan pattern, or automatically varied for surveillance or tracking applications. A pre-calibrated look up table is used to vary the reflective spatial light modulator for each fixation point.
