Abstract

An optoelectronic structure for implementing the iterative filtered-back projection image reconstruction algorithm is proposed. The forward projection and back projection operations in the iterative procedure are performed via optoelectronic devices, which include spatial light modulators and charge coupled device detector arrays. The optical Fourier transform is applied to speed up the reconstruction and feed-back is used to minimize the distortion caused by optical transforms.
