【摘要】 近年来,体全息存储技术以其存储容量大、数据传输率高和具有相关识别等特性被广泛研究。而基于散斑参考光的体全息散斑复用技术能够比传统的复用方法提供更小的复用间隔和更高的存储密度。在本文中,我们在理论上和实验上分析了散斑复用技术的两个突出优点,为大容量高密度体全息存储打下了理论基础。更多还原

【Abstract】 Recently, volume holography technology is widely studied because of its high storage density, fast data transfer rate and the correlate character. The newly proposed speckle multiplexing scheme could provide smaller multiplexing selectivity and higher storage density compared with other conventional schemes. In this paper, two noteworthy merits of speckle multiplexing scheme are analyzed both theoretically and experimentally. This work gives a theoretical fundament for the high density volume holographic storage.更多还原
