It has been shown that the principal cause of flare light in a bleached hologram is self-interference of light from an extended object. In most bleaching processes the surface relief image and variation of refractive index of the bleached emulsion combine to enhance the self-interference pattern at low spatial frequencies and thus to enhance the flare light. This paper describes a reversal bleach process for Kodak spectroscopic plates, Type 649-F, such that the relief image tends to cancel the effects of the index variation for low spatial frequencies. This makes it possible to achieve high diffraction efficiencies and signal-to-noise ratios. Data are given.
已经表明，漂白全息图中耀斑光的主要原因是来自扩展物体的光的自干涉。在大多数漂白过程中，表面浮雕图像和漂白乳剂折射率的变化相结合，以增强低空间频率下的自干涉图案，从而增强耀斑光。本文描述了一种适用于柯达649-F型光谱板的反转漂白工艺，使得浮雕图像倾向于抵消低空间频率下折射率变化的影响。这使得实现高衍射效率和信噪比成为可能。给出了相关数据。
