Abstract
Selected embodiments include an imager providing wide field (WFOV) and foveated images. The imager includes a frontend optic receiving light. Corrective optics reduces distortions, and transmits the light to a splitter. One portion of the light exiting the splitter is focused on a WFOV image detector. A second portion falls on a scanning mirror targeting a selected field position. The light is corrected by an adaptive corrector, which may be configured for field position-dependent correction. The light from the corrector is focused on a foveated image detector. An eye tracker may be employed to select the foveated position corresponding to user gaze direction. Another imager includes a configurable corrector in the imager's optical stop. Free space optical (FSO) communication laser may be combined with a foveated/WFOV imager, with a corrector of the imager correcting the FSO light and a scanning component selecting transmission direction for the FSO light.
