利用可控光学透明光栅(简称可控光栅)记录全息档案信息得到实现。讨论了用档案作为输入资料原稿时对可控透明光栅提出的要求。叙述了所使用液晶的可控光栅结构。给出了用可控光栅获得的图象和再现全息图象的特性。指出了改善图象质量的途径。 The use of controlled optical transparent grating (referred to as controllable grating) to record holographic file information is achieved. Discusses the requirements for controllable transparent gratings when using files as input documents. The controllable grating structure of the liquid crystal used is described. The properties of images obtained with controllable gratings and the reproduction of holographic images are given. Point out ways to improve image quality.
