In coded aperture imaging the attainable quality of the reconstructed images strongly depends on the choice of the aperture pattern. Optimum mask patterns can be designed from binary arrays with constant sidelobes of their periodic autocorrelation function, the so{called URAs. However, URAs exist for a restricted number of aperture sizes and open fractions only. Using a mismatched lter decoding scheme, artifact{free reconstructions can be obtained even if the aperture array violates the URA… CONTINUE READING
