卤化银感光材料的计算机应用研究(Ⅱ)——信道容量测试

A Study on Photographic Material AgX by Using Computer (Ⅱ)-Measurement on Channel Capacity

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.

Authors contribute a measurement and calculation program on the PDS microdensitomete-computer system and realize automatic measurement on channel capacity of AgX photographic ma?erial.This work is based on the Shannon's information theory and photochemical measurement m?thod,and treated the AgX photographic material as a transmission channel of information.Experi?ents show that this measurement has the advantages of high accuracy and high speed.It is a good method of evaluation for photographic materials.
