Abstract
A digitally scanned multi-cell EO sensor comprises a low-resolution multi-cell imaging detector. An array of optical focusing elements decomposes the sensor's FOV into at least four sub-fields. A sub-field directing array and focusing optic direct the optical radiation onto the imaging detector. In a first tilt mode, the optical radiation from the sub-fields is directed into at least four spatially separated sub-regions that each map to a different detector cell. A high-resolution spatial light modulator (SLM) digitally scans the FOV to select different portions of the FOV to map onto the different detector cells to time demultiplex spatially overlapping portions of the FOV onto each detector cell to stitch together a sub-image of a selected area of the FOV up to the native resolution of the SLM.
