| 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. |
