  • Abstract
    An iterative reconstruction technique that is guaranteed to converge to the unique minimum-norm solution is proposed. The iterative algorithm allows the reconstruction of the cross-sectional image by simple projecting images between the image display and detector arrays iteratively without employing computation intensive operations, such as Fourier transforms, convolutions or interpolations. A high speed optoelectronic implementation of the algorithm is also presented. The closed-loop structure reduces distortions introduced in common optoelectronic systems. The structures can be built using off-the-shelf devices and were shown to result in high accuracy reconstructions
