CCD技术应用于研究物理显影过程

本文使用一个线性CCD器件,通过反射光强(Intensity)随CCD单元及反应时间的变化,直接监测感光化学中银盐扩散转移体系中的物理显影过程,主要研究了加工液组分对物理显影的影响。实验结果表明,当使用KSCN作为银络合剂时,对苯二酚为显影剂,物理显影速率随络合剂浓度的增加而增加,随显影剂浓度的增加而下降;用Na₂S₂O₃为络合剂时,其结果相反;当用尿嘧啶为银络合剂时,显影剂浓度在0.1mol/L时反射光强出现最佳值。与此同时还研究了保护剂、溶液pH值等条件的影响。本文证明了CCD方法用于研究物理显影是可行的。

THE MONITORING FOR PHYSICAL DEVELOPING PROCESS WITH A LINEAR CCD

In this paper,a linear CCD was used to detect the whole physical developing process of silver diffusion transfer reversal process in photographic chemistry,and the physical develop-ing rate was obtained by the change of reflected intensity of metallic silver with the cells of CCD and the reacting time. The influence of the ingredient of the working solution was studied. The results indicated that when KSCN was used as the silver complexing gent,and hydroquinone as the developer,the rate of physical development increased with the raising of the concentration of KSCN,and decreased with the raising of the concentra-tion of hydroquinoe,but the results were contrary when Na₂S₂0₃ was used as the silver tom-plexing agent instead of KSCN. However,there was the best result-hen the concentration of hydroquinone was suitable,using uracil as the silver complexing agent. The influence of the protector and the pH on the metallic silver in physical development was also studied. It was proved that this method was available in the study of physical development.
