Abstract

Digital holography is technique for registering of 2D- and 3D-scenes characteristics: amplitude or phase images of object, roughness, and etc. Numerical reconstruction allows fast images recovery. However high quality optical reconstruction is not so fast due to the hologram transferring to the spatial light modulator (SLM), hologram digital preprocessing, SLM calibration, and etc. In this work we analyzed possibilities of fast processing of the holograms for increasing of quality of optically reconstructed images. Amplitude type holograms were registered and images were optically reconstructed using phase liquid crystal SLM. Various techniques of improvement of reconstruction quality were used.
