摘要： An optical correlation apparatus is taught which provides a parallel optical signal having a phase modulation representing input data to which a parallel phase modulation based on reference data is applied. In the event of correlation the resulting wavefront is planar and can be interferometrically coupled to give a high intensity signal. The invention involves use of parallel amplitude modulation means for selectively blocking the optical signal in one or more of the channels of the parallel optical signal which allows different sized reference data strings to be searched more easily and also aids in calibration.

摘要： In coded aperture imaging knowledge of the coded array pattern and its positional relation to the detector array is needed in order to be able to reconstruct the scene image. Usually a theoretical model of the coded array is used and the actual array needs to be aligned accurately with respect to the detector. The present invention uses a coded aperture imager to image a reference object in the scene and uses the intensity pattern on the detector array to determine the decoding pattern corresponding to the coded aperture array. The reference object may be a point source in which case the pattern on the detector array may be used directly as the decoding pattern or it may be used to correct a theoretical pattern for any misalignment.

摘要： The present invention relates to processing of coded aperture images. Multiple frames of data acquired by the coded aperture imaging system, each with a different coded aperture array, are processed to form an image. The processing incorporates the constraints that the image solution must be positive and that the solution should be zero outside an expected image region. In one embodiment image enhancement may involve dividing the processed image into image regions having a spatially invariant point spread function and solving an inverse problem for each image region to reduce image blurring.
