摘　　要：全息数据存储凭借其高存储密度、快速读取速度及长期数据保持能力等优势,已成为应对海量数据存储需求的理想选择。系统地回顾了全息数据存储复用技术的研究进展,包括离轴型、同轴型、基于计算机生成全息图型和自参考型全息数据存储装置,阐述了它们基于角度和移位变化的空间复用和基于振幅、相位和偏振调制的正交/非相关复用两大类别下的具体应用。空间复用技术主要通过精确调控参考光和物光之间的夹角或相对空间位置来实现信息的高效多址存储。而正交/非相关复用技术则利用光的振幅、相位及偏振等基本物理属性进行信息编码从而实现数据存储。不同类型的全息数据存储装置在复用技术上展现出各自的独特优势,为构建高密度、大容量存储系统奠定了坚实基础。随着材料科学、光学工程及信息技术的不断革新与发展,全息数据存储复用技术有望迎来更多突破,为数据存储领域注入新的活力与发展机遇。Dennis Gabor's groundbreaking contributions in the 1940 s initially illuminated the enigmatic and potentially boundless field of holography.Over the subsequent decades,through his relentless perseverance,he continuously deepened and refined the theoretical framework of this technology.Holography,once perhaps confined to the realm of scientific fancy,gradually evolved into a pivotal tool for exploring new horizons in information storage,led by Gabor's visionary guidance.As the 1960s dawned,the rapid advancement of science and technology paved the way for Van Heerden,who,with his prescient vision,boldly foresaw the vast potential applications of holographic technology in data storage.This idea,akin to a seed,swiftly germinated and flourished with the nourishment provided by laser technology.The emergence of lasers furnished the crucial light source necessary for holographic data storage technology,thereby transitioning holographic data storage from theoretical discourse to practical implementation and gradually positioning it as a shining star in the landscape of next-generation optical storage.The unique advantage of holographic optical data storage resides in its unprecedented capacity to store information in a three-dimensional space within the recording medium.This distinctive feature allows for the parallel writing and reading of data,in stark contrast to traditional two-dimensional data transmission methods.By adopting this three-dimensional storage approach,holographic data storage technology not only vastly enhances storage capacity but also markedly boosts data transmission speed.Consequently,holographic data storage demonstrates unparalleled superiority in addressing the challenges posed by the big data era.The core of holographic data storage technology hinges on the volumetric recording of spatial light wave distributions,ushering in an entirely novel mode of data page storage.Leveraging the selective properties of thick holograms,holographic data storage facilitates parallel data processing and multipl
