14-2 計算機ホログラフィの視域の改善

抄録

The single-sideband method cuts off light beams coming from conjugate images in holography using amplitude modulation. This method in combination with half-zone plate processing restricts the viewing zone within narrow range and also causes shading. We have proposed a method to improve these restriction and deterioration by time-alternate switching of hologram and a spatial filter set on the focal plane.
