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.
