摘　　要：实验研究了自制的超细颗粒卤化银乳剂 SDUF- 1分别在 AAC显影、改进的 R- 10漂白处理及改进的 GP- 8溶解物理显影处理条件下 ,其乳胶厚度对反射全息图衍射特性的影响。实验结果表明 ,在这两种不同处理条件下衍射效率与胶厚的关系有相当大的差别 ,合适的乳胶厚度分别为 12μm和 6μm左右。Ultra fine grain silver halide red sensitive emulsion SDUF 1(15 nm average grain size) with two different processing methods was prepared in this paper.Reflection gratings were recorded in the emulsions of different thickness raging from 5 to 15 μm with various exposures,and processed in the following two ways:in the developer AAC and the bleach modified R 10,and in the solution physical developer modified GP 8.The diffraction properties of the reflection gratings,such as peak diffraction efficiency,reconstruction wavelength and half width,were measured using a monochromator system combined with an integrating sphere.It is shown that the diffraction properties versus the emulsion thickness for the gratings processed in the above two ways are widely different from each other,and the optimums of the emulsion thickness for the two processing methods are about 12 and 6 μm respectively.
