摘　　要：通过实验优化重铬酸钾、碘化钾和浓硫酸漂白液的配比 ,使其适合于处理用超细颗粒卤化银乳剂SDUF- 1记录的反射全息图。用 SDUF- 1乳剂记录的反射全息光栅经 AAC显影液和优化的漂白液处理后 ,其衍射效率和信噪比分别达 5 0 %和 5 0 ,且乳剂收缩引起的布喇格角偏离小于A bleach composed of potassium dichromate, potassium iodide, sulfuric acid is optimized for processing reflection holograms recorded in the ultra-fine-grain silver halide emulsion SDUF-1. Diffraction efficiencies (DE) of 50% and signal-to-noise ratios (SNR) of 50 are obtained for reflection holographic gratings recorded in the SDUF-1 emulsion, processed with the AAC developer and the optimized bleach. Moreover, the deviation of the Bragg angle caused by the emulsion shrinkage is less than 3°.
