New vacuum ultraviolet imaging detector

The development of ultraviolet warning and its key device is introduced, including the characteristics and development of ultraviolet warning, ultraviolet radiation transmittance and the development of ultraviolet detector. A new vacuum ultraviolet detector is described, its photocathode is a solar-blind, a proximity focus tube with less dispersion and image distortion is adopted, its read-out system has light-coupling and electricity-coupling, the light-coupling read-out system is simpler and responds in real time, the electricity-coupling read-out has high sensitivity and resolution as well as long detection distance. Auto gating BSP power supply is adopted to extend dynamic range, protect photocathode and microchannel plate.
