The Coupled Wave Theory of Kogelnik has given a wellestablished basis for the comprehension of how light propagates inside a hologram. This theory gives an accurate approximation for the diffraction efficiency of volume phase holograms and volume absorption holograms as well. Mixed holograms (phase and absorption) have been also treated from the point of view of this theory. For instance, Guibelalde theoretically described the diffraction efficiency of out of phase mixed volume gratings. In this work we will show that when using fixation-free rehalogenating bleaches, out of phase mixed volume gratings can be recorded on the hologram at high exposures. This is due to the oxidation products of the developer and the bleaching agent. The effects described theoretically for out of phase mixed volume hologram gratings are experimentally observed.
科格尔尼克的耦合波理论为理解光在全息图中的传播方式提供了坚实的基础。该理论对体相位全息图和体吸收全息图的衍射效率也给出了精确的近似。混合全息图（相位和吸收）也从该理论的角度进行了探讨。例如，吉贝拉尔从理论上描述了异相混合体光栅的衍射效率。在这项工作中，我们将表明，当使用无定影再卤化漂白剂时，在高曝光量下可以在全息图上记录异相混合体光栅。这是由于显影剂和漂白剂的氧化产物所致。理论上描述的异相混合体全息图光栅的效应得到了实验观察。
