Abstract
A detector with a non-uniform spatial sensitivity measuring an image. From the measured outputs, the image can be re-constructed by a signal processing scheme. In a preferred embodiment, an array of such detectors, each with an imaging surface and a non-uniform spatial sensitivity across the surface, is used to measure the image. In another preferred embodiment, the detector(s) measures the image more than once, each time with the relative position between the image and the detector(s) changed. The measured outputs are interlaced together and deconvolved by an inverted model of the detector(s) to re-construct the image.
