摘要

分析了日盲电晕探测中探测器紫外ICCD相机噪声的构成特性

利用试验方法统计了PROXITRONIC 公司第二代紫外ICCD相机不同增益下的光电阴极暗电子发射散粒噪声水平

提出了基于统计数据的阴极噪声的抑制方法

实现了对紫外ICCD相机散粒噪声的抑制。将此方法应用到电晕探测过程

实验结果证明了该方法对图像噪声的抑制有效

保持了相机的动态范围。

Abstract

The noise sources and its characteristics of a ultraviolet camera based on generation Ⅱ ICCD were analyzed. Ultraviolet ICCD made by PROXITRONIC company was tested to give shot noise statistic data of the photocathode

which indicates the relationship between various MCP gain and shot noise created by photocathode. Based on statistic data

a restraining photocathode noise method was introduced to restrain the photocathode shot noise and decrease the affection on image processing. Application of this method to corona detection

results show that this method is a availability in restraining image noise and keeping the dynamic range of the camera.
