Optical computing in tomographic problems

摘要

Abstract: Emission or propagation of optical irradiation through cylindrical objects can be described by the Abel equation. Only some of the numeric solutions have satisfactory accuracy. They provide convergence of outcome function but greatly increase calculation time. One of the ways to increase the speed of calculation is by optical processing of signal. Ultrafast processing never before realized with conventional electronics is available in decision of inverse problems. In the study we use optical derivation of a signal. Derivation of phase is easy in interference tomography. Mathematical algorithms became faster. !2
