Paper Abstract

When the computer generated hologram ( CGH ) is applied for the optial memory, it is necessary to make CGH in real time and to reconstruct the image in the original place. For this purpose some kinds of direct laser recording system for making CGH were proposed by now but these procedures were so complicated that it was difficult to construct these systems. On the other hand electron beam recording methoewas proposed for the direct recording of CGH. In this case special setup such as the vacuum equipment is necessary to use the electron beam, so it is not easy to make CGH and to reconstruct the image in the original place.
