低剂量γ辐射对视频品质的影响及其改善方法
Effect of Low Dose Gamma Radiation on Video Quality and Improvement Methods
摘要
Abstract
Irradiation experiments of CMOS image sensor have been presented by 60Coγ￣ray resource.Influence factors of video quality degradation were analyzed by damage mechanism. And the improvement methods about reduced radiation effect were put forward. The average brightness and color channel intensity of the collected monitoring frame have been analyzed by irradiation experiments.As the results showed,the average brightness and the number of noisy point of monitoring frame increased with the total ionizing dose increasing,also with green color cast.Irradiation effect of CMOS image sensor monitoring frame could be improved by the methods as follows:separating sensor part from the signal processing part,adding radi￣ation shielder;using the radiation resistance photodiode with shallow trench isolation and lower pinch off voltage.Color balance could also be adjusted by software program.关键词
