【摘要】 本文提出了一种用于动态-静态散斑复用(DSSM)体全息存储技术的曝光时序,在顺序曝光法的基础上引入一个擦除因子,来补偿由于静态散斑复用造成的擦除效应。实现了动态-静态散斑混合复用方式下的均匀的复现衍射效率。采用这套时序公式实验并记录了400幅全息图,实验结果也进一步证明了时序公式的可行性。更多还原

【Abstract】 An exposure-schedule theory of uniform diffraction efficiency forDynamic-Static speckle multiplexing volume holographic storage is proposed. Anoverlap-factor is introduced into the system to compensate the erasure effect of thestatic speckle multiplexing scheme. The exposure-schedule which is an inverserecursion formula is deduced. Experimental results are obtained in a LiNbO3:Fecrystal and 400 holograms with uniform diffraction efficiency are achieved by use ofthe new exposure-schedule.更多还原
