Abstract
We have simulated the performance of various apertures used in coded aperture imaging—optically. The annulus, twin annulus, Fresnel zone plate and the uniformly redundant array have been decoded using a non-coherent correlation process. Ways of reducing the ‘d.c.’ background of the various apertures are discussed. Results of imaging extended and continuous-tone planar objects are presented.Keywords
