由天津市电子计算机研究所激光室研制成的该套设备已于1984年6月29日通过鉴定。由天津市科委组织,邀请了全国和天津市的95名光学专家、科技工作者和使用单位等的代表参加了这次鉴定会。该设备包括超缩机、拷贝机、阅读器、复印机和记录介质。在6″×4″的新型记录片上能拍摄3010个全息点,点中心间距为2毫米。每点能记录1～2页(最高4页)16开资料。在一个片上可记录四年《中国激光》,也可记录12,000页《红旗》杂志;用它拍摄的非漂白全息光栅,其+1级衍射效率达45％左右(最高达50％)。在超缩机上新设计了一种没有 The set of equipment developed by the Tianjin Institute of Electronics Computer Laboratory was approved on June 29, 1984. Organized by the Tianjin Science and Technology Commission, 95 optical experts, scientists, technicians and users from the whole country and Tianjin were invited to attend this conference. The equipment includes super-miniature machines, copy machines, readers, copiers and recording media. On the new 6 “x 4” documentary, 3010 holograms can be recorded with a 2mm center-point spacing. Each point can record 1 ~ 2 pages (up to 4 pages) 16 open data. It can record four years of “China Laser” on one slice and 12,000 pages of “Red Flag” magazine. The non-bleached holographic gratings recorded with it have a +1 order diffraction efficiency of about 45% (up to 50%). In the super-shrink machine designed a new
