发明名称 HOLOGRAPHIC RECONSTRUCTION SYSTEM HAVING AN ENLARGED VISIBILITY REGION
摘要 The invention relates to a holographic reconstruction system for the reconstruction of scenes having at least one video hologram modulated wave front, and an enlarged visibility region. The system utilizes two-dimensional coded light modulator cells of spatial light modulation means and optical focusing means, which realize a Fourier transformation of the modulated wave front in their focal plane. First optical deflection means deflect the parallel disposed partial light waves such that their Fourier transformations appear as cascading in the focal plane. A spatial frequency filter located on the focal plane, lets each of the same diffraction orders of all modulated partial light waves pass, and second optical deflection means arrange the wave front strips next to each other at the modulated wave front, which reconstructs the scene.
