Abstract
A foveated imaging system using a relatively simple optical imaging system with a spatial light modulator located at or near a pupil plane to correct aberrations. Maximum resolution is obtained for a limited region defined by a single fixation point (a foveal region) within the field of view. The fixation point can be changed manually, by using a predetermined scan pattern, or automatically varied for surveillance or tracking applications.
