摘　　要：大数据时代对数据存储提出了新的要求,为克服目前存储技术无法逾越的障碍,全息存储回到人们的视野,为了解决传统全息存储的记录密度与理论值相差较大的问题,本文作者团队提出了将光的振幅、相位和偏振均作为调制变量的多维调制全息数据存储技术;为验证多维调制的实验结果,针对具有偏振响应的全息存储材料特性提高方面也开展了研究。这些研究成果加速了全息存储技术应用的产业化步伐。本文以该团队在北京理工大学期间开展的多维调制全息数据存储技术的研究成果为基础,分别从光的振幅、相位和偏振调制机理出发,综述了各个调制方法的理论基础和应用实例,以及提高全息存储材料性能的有效手段,最后进行了总结和展望。Background The holographic optical storage method stores information in a three-dimensional space of the recording medium,and writes and reads it in parallel with two-dimensional data transmission.Therefore,it features large capacity and high speed that traditional optical discs cannot match.As early as the 1960s,this method was hailed as a high-density and high-speed data storage method.However,due to the lack of good recording materials at that time,it only remained in conceptual research and did not develop well.Throughout the development history of holographic optical storage,every major progress depends on the materials.In the 1990s,people employed the photorefractive effect of crystals to carry out volume holographic data storage,which once became a research hotspot with many ingenious designs being proposed.AT&T,Bell lab,IBM,RCA,and 3M in the USA,Thompson CSF in the UK,NEC and Hitachi production institute in Japan,and California Institute of Technology and Stanford University in the USA have attempted to study holographic optical storage.After entering the 21st century,companies represented by InPhase and Aprilis in the USA proposed photopolymer as a holographic optical storage material,with a data storage life of up to 50 years.Japan's Optware company has taken a significant step towards the productization of holographic optical storage technology with its unique collinear holographic optical storage method which can effectively avoid interference from environmental vibrations.However,there is still a significant gap between the actual recording density and the theoretical value of holographic optical storage technology.The reason is that there are too few parameters available for modulation in traditional holographic optical storage technologies.Using various parameters of light for multi-dimensional modulation,the recording density of holographic optical storage can be further improved to fully utilize the original capabilities of holographic optical storage.However,how to record and read multi-dimensio
