HOLOGRAPHIC 3-DIMENSIONAL DISPLAY USING AN ELECTRON-BEAM-ADDRESSED SPATIAL LIGHT-MODULATOR

Three-dimensional (3-D) or holographic information extracted by two-di mensional active optical heterodyne scanning has been demonstrated rec ently. The technique is called optical scanning holography. To reconst ruct the obtainable 3-D holographic information, digital techniques ha ve been used and demonstrated. For real-time applications, we need to investigate spatial-light-modulator-based systems. In this paper, we f irst briefly review optical scanning holography, and then present expe rimental results of 3-D image reconstruction using an electron-beam-ad dressed spatial light modulator.
