Abstract

A new universal low computational complexity algorithm for numerical reconstruction of holograms recorded in near diffraction zone is presented. The algorithm implements digital convolution in DCT domain, which makes it virtually insensitive to boundary effects. It can be used for reconstruction of holograms for arbitrary ratios of hologram size to the object-to-hologram distance and wavelength to camera pitch and allows image reconstruction in arbitrary scale.
