【課題】音響光学変調器を備えた配置は非常に嵩張り、最新式のフラットディスプレイで知られている寸法まで縮小できない。小型、広視野角の映像ホログラムの拡張リアルタイム再生を提供する。【解決手段】映像ホログラムと、光源１、レンズ２、および、マトリックスまたは規則的なパターンに配置されたセルからなり、１セルごとに少なくとも１個の開口を備え、上記開口の位相または振幅が制御可能である映像ホログラム３により構成された光学系を具備する映像ホログラム再生装置とする。【選択図】図３ The device has an optical system with a light source(s) and lens. The video hologram has cells, e.g. in a matrix, with an opening(s) per cell of controlled amplitude/phase and an observation plane. An observation window in the observation plane at a periodicity interval of the reconstruction as a Fourier transform of the video hologram enables viewing of a three-dimensional scene. The window size is not greater than the periodicity interval. The device has an optical system consisting of at least one real or virtual point- and/or line-shaped, adequately coherent light source (1) and a lens (2) and the video hologram (3) consists of cells in a matrix or other regular arrangement with at least one opening per cell of controlled amplitude and/or phase and an observation plane at the location of the light source image. An observation window (5) is located in the observation plane at a periodicity interval of the reconstruction as a Fourier transform of the video hologram for observation of a three-dimensional scene (6). The size of the window is not greater than the periodicity interval.
