本文将卤化银感光材料作为一种信息传输通道,按照香农信息理论和感光化学测定方法,在PDS程控显微光密度计系统和计算机上发展了测试和计算程序,实现了信道容量的自动化测试.实验证明,这种测试方法精度高,速度快,是感光材料研究的好方法. In this paper, silver halide photographic materials as an information transmission channel, in accordance with the Shannon information theory and photochemical chemistry determination method, the PDS program-controlled micro-optical density meter system and computer developed test and calculation procedures to achieve the channel capacity of automated testing. Experiments show that this test method with high precision and fast speed, is a good method of photosensitive materials.
