摘要： The invention relates to a light modulator for representing complex-valued data, comprising an encoding area that has an arrangement of pixels, the phase of which can be controlled. The aim of the invention is to largely avoid an interfering optical path difference between adjacent pixels or pixel groups when a complex value is encoded in several adjacent phase pixels of the encoding area, said optical path difference varying according to the angle. Said aim is achieved by associating one respective specific structured delaying layer which causes the optical path of an incident linearly polarized beam to change according to the angle, with at least one predefined pixel of a group of adjacent pixels of the encoding area (2). The thickness (d) of said delaying layer is designed such that the modification of the optical path caused by the delaying layer runs in the opposite direction from the angle-related modification of the optical path difference between individual pixels of the pixel group and at least partly or fully compensates the angle-related modification of the optical path difference.

摘要： The invention relates to a method of and apparatus for displaying a holographically generated video image having plural video frames. For each frame there is provided and computed (20) a respective sequential plurality of holograms. Each said sequential plurality of holograms of the plural video frames are sequentially displayed on a diffractive element (12) for viewing the replay field thereof, and the noise variance of each frame is perceived as attenuated by averaging across said plurality of holograms.
摘要翻译：本发明涉及用于显示具有多个视频帧的全息产生的视频图像的方法和装置。对于每个帧，提供并计算（20）相应的顺序多个全息图。多个视频帧中的每个所述顺序多个全息图被顺序地显示在用于观看其重放场的衍射元件（12）上，并且通过在所述多个全息图之间的平均来感知每帧的噪声方差被衰减。
