Paper Abstract

The paper considers the use of holographic interferometer for hologram re-recording with correction of distortions. Each optical system contains some beam path deviations, called aberrations of the optical system. They are seen in the resulting interference pattern as a distortion of fringes. While increasing the sensitivity of the interference pattern by N times at the same time we introduce new aberrations, caused by re-recording setup in addition to aberrations that are already presented on the interferogram, caused by initial recording, also multiplied by N times. In this experiment we decided to use a modified setup with spatially combined interferograms with use of matrix spatial light modulator and digital image processing of the interferograms recorded by CCD or CMOS camera.
