Description

technical field

[0001] The invention relates to a signal processing structure and method of an ultraviolet corona detection device based on an ultraviolet photon pulse counting image detector, belonging to the field of corona detection. Background technique

[0002] In recent years, ultraviolet corona detection technology has developed rapidly. The core detectors mainly include ultraviolet CCD, enhanced charge-coupled device ICCD and ultraviolet photon counting image detector. At present, most of the ultraviolet corona detection equipment adopts the first two detectors. Ultraviolet photon counting image detectors are rarely used, but the first two detectors need to be imported from abroad and are expensive, especially the ultraviolet CCD is very expensive, which is not conducive to domestic independent production of ultraviolet corona detection equipment. Therefore, a method based on The signal processing structure and method of the ultraviolet corona detection equipment of ...
