Abstract

Numerical simulation and real experiments of obtaining tomographic projections were performed, and iterative algorithms for diffraction and transmission tomography for image reconstruction were developed. The generalization of one of the most promising type of iterative algorithms - Gerchberg-Papoulis algorithm for diffraction tomography was constucted. In addition, experimental methods for registration of tomographic projections in the terahertz range were developed. All measurements were carried out using real-time image sensor: a luminescence-quenching thermal image plate with an intensified CCD camera.
