20140104475 | LENSLESS IMAGING CAMERA PERFORMING IMAGE FORMATION IN SOFTWARE EMPLOYING MICRO-OPTIC ELEMENTS CREATING OVERLAP OF LIGHT FROM DISTANT SOURCES OVER MULTIPLE PHOTOSENSOR ELEMENTS - A lensless camera with image formation performed by image processing software rather than by lens. Image formation operations are coordinated with a micro-optical element array that can comprise apertures, micro-optic layers, etc. configured so light received from a distant source overlaps onto multiple photosensors. Algorithms for image formation are determined by pixel overlap functions resulting from micro-optic elements directing light to a photosensor array, and can include deconvolution, edge-effect handling, decimation, and interpolation. Image formation operations can comprise frequency-domain operations or other approaches. The micro-optical element array can be configured to produce a spatial light pattern on the photosensor array with optimized detection characteristics. Light-detecting photosensors can comprise elements capable of light emission, for example organic materials with electroluminescent properties. The camera can be implemented or integrated upon any one of a wide variety of surfaces or substrates. Fabrication can employ techniques from semiconductor processing and flat panel display manufacturing. | 04-17-2014 |
