The mechanism for hologram formation by fixation-free rehalogenating bleaching has been treated by several authors. Experiments carried out with Kodak and Agfa photographic plates have led to the conclusion that the transfer of material from the exposed to the unexposed zones is the main mechanism that drives the process. We show that when BB-640 emulsion is used in the recording of holograms by means of fixation-free rehalogenating bleaching, the mechanism for the transfer of material from exposed to unexposed zones is efficient enough to create high refractive-index modulations. We also comment on the overmodulation effects, which result in a decrease in diffraction efficiency.
多位作者探讨了通过无定影再卤化漂白形成全息图的机制。使用柯达和爱克发照相底片进行的实验得出结论，物质从曝光区转移到未曝光区是驱动该过程的主要机制。我们表明，当使用BB - 640乳剂通过无定影再卤化漂白记录全息图时，物质从曝光区转移到未曝光区的机制足以产生高折射率调制。我们还对过调制效应进行了评论，过调制效应会导致衍射效率降低。
