Holographic Screening of Dynamic Real Scenes

摘要

Computer generation of holograms is a technique used to obtain a specific laser intensity distribution in far field starting from a desired image. In the process of hologram computing, the phase information must be considered. In this study we will present our code which ensures a fast link between the CCD camera (which records real macroscopic scenes), computer (where holograms are generated) and the spatial light modulator (where the holograms are displayed) to obtain on a screen a holographic displayed movie in real time. The aim of this work was to build interactive holographic systems. The challenge was not only to develop such a code, which can work for a suite of images taken by the CCD, but also to process them in a way that the delay of resulting reconstruction is unperceivable for human eye. For the veracity of the method we will present both simulation and experimental results.
