【摘要】 实验制备了颗粒平均尺寸为10mm且具有一定的红、绿和蓝色灵敏度的超细颗粒卤化银乳剂,对影响颗粒尺寸和光谱灵敏度的若干制备条件进行了讨论;实验研究了用该乳剂记录的反射全息光栅的衍射特性。实验结果表明,用改进了的AAC显影液和R 10漂白液处理,当用红光(633nm)或绿色(515nm)记录时,反射全息光栅的衍射效率可达55%,需要的曝光量分别为1.8mJ/cm2、2.2mJ/cm2;当用蓝光(458nm)记录且曝光量为3.3mJ/cm2时,衍射效率达50%。更多还原

【Abstract】 Silver halide emulsions with average grain size around 10 nm and red-green-blue sensitivities were prepared.The influences of some preparing conditions on the emulsion grain size and spectral sensitivity were discussed.The emulsions were used to record holographic reflection gratings for investigating their properties in reflection holography.The reflection gratings were processed in a modified AAC developer and modified R-10 bleach.Diffraction efficiencies of the reflection gratings achieve 55 % for the exposure of 1.8 mJ/cm~2 at 633 nm,55 % for the exposure of 2.2 mJ/cm~2 at 515 nm and 50 % for the exposure of 3.3 mJ/cm~2 at 458 nm respectively.更多还原
