Title: Device for recording hologram
Inventor: KIM GEUN YUL
IPC: G11B7/128
Filed: 1998-12-28
Abstract: PURPOSE: A device for recording a hologram is provided to promptly and uniformly record data by projecting the data represented as a P-S polarized beam from a spatial light modulator. CONSTITUTION: A spatial light modulator(150) is a kind of LCD(liquid crystal display) and does not have a polarized beam filter on a rear surface. When an electric field is applied to upper/lower transparent electrodes(151,153), liquid crystals in pixels are horizontally arranged on a liquid crystal surface. Thus, the polarized beam in a signal beam passing through the pixel is converted. When the electric field is not applied, the liquid crystals are vertically arranged. Thus, the polarized beam is not converted. Therefore, the spatial light modulator includes an image signal data representing the signal beam as P-S polarized pixels.
