全息数据存贮的时代终于来临,这种存贮是六十年代中期激光全息术出现以来引起光学研究人员兴趣的一个概念。美国奧斯汀微电子学计算机技术公司(MCC)已获得了实际系统两种关键方法的专利,它们是光折变材料的非破坏性读出和使用小型圆柱形细晶体(而不是块状晶体)的存贮器。MCC全息图数据在铌酸锶钡光折变材料制作的空间光调器中显示。 The era of holographic data storage has finally come to an end, a concept that has aroused the interest of optical researchers since the advent of laser holography in the mid-1960s. Austin Microelectronics Computer Technologies Inc. (MCC) of the United States has patented two systems that are actually systems critical for non-destructive readout of photorefractive materials and the use of small, cylindrical, fine crystals (rather than bulk crystals) Memory. The MCC hologram data is shown in a spatial light modulator made of barium strontium niobate photorefractive material.
