Abstract
An optical imager includes a sensor and a diffraction lenticular array. The sensor includes a substrate of a semiconductor material having a pair of opposed major surfaces and a plurality of photodetectors arranged in a plurality of columns along one of the major surfaces. The diffraction lenticular array includes a plurality of stripes of a material which will diffract the radiation being sensed. The stripes are arranged in a plurality of repetitive patterns with each pattern being formed of a plurality of spaced, parallel stripes extending longitudinally along a column of the detectors. The pattern of the stripes has a large spacing between the stripes at the center of the pattern and smaller spacing at the edges of the pattern. The stripes may be on a separate substrate of a material which is transparent to the radiation being detected or directly on the major surface of the semiconductor substrate.
