摘要：
A new coded aperture system design for use with circular detectors is discussed, whereby square element coded aperture unit patterns are mosaiced onto a circular detector with a view to maximising the size of the unambiguous field of view for any given detector radius. The results for these optimum configurations are presented for all 50% transparency URA and MURA unit patterns of order v < 600. Improvements in the FOV size over standard rectangular mosaicing are presented with the available increase being found to be around 23% for large values of v.
