Abstract

The invention provides a solar-blind ultraviolet camera ultraviolet light detection sensitivity test system and a test method. A laser pumped broadband light source generates broadband white light with high brightness and high stability and the light is emitted to a double-cascade monochrometer system. Under control of a computer, the double-cascade monochrometer system generates needed ultraviolet monochromatic light. The monochromatic light output by the monochrometer passes through an integrating sphere and then is converted into monochromatic uniform light, the light is attenuated by an ultraviolet attenuation sheet and then is emitted to a solar-blind ultraviolet camera. Light power of the monochromatic light output by the integrating sphere can be displayed by an intelligent power meter system in real time. A photon number output by the solar-blind ultraviolet camera is collected to a computer through a serial port. If an average number of photons in a bright environment is equalto an average number of photons in a dark environment, a power density of the light emitted to the solar-blind ultraviolet camera is ultraviolet light detection sensitivity.

Description

technical field [0001] The invention relates to the technical field of solar-blind ultraviolet detection equipment, in particular to a test system and a test method for ultraviolet light detection sensitivity of a solar-blind ultraviolet camera. Background technique [0002] Solar-blind UV cameras are mainly used for UV corona discharge detection. At present, the supply and consumption of domestic power resources are very unbalanced. The north-to-south power transfer and west-to-east power transfer promote the rapid development of high-voltage power transmission technology and smart grid technology in China. The main technology is to ensure uninterrupted power transmission, but Corona discharge will cause the power interruption of the whole grid, so it is imperative to monitor it. Since the main spectrum of corona discharge belongs to the ultraviolet band, the sun-blind ultraviolet detection camera is the best observation device. [0003] Ultraviolet light detection sensiti...
