Ultraviolet imaging technology is a non electric corona testing technology, which uses ultraviolet imager to detect ultraviolet produced by air discharge ionization, and then determine the position and intensity of corona discharge, it has high accuracy and reliability. For the detection and calibration of UV / visible image coincidence of UV imager, the LED integrating sphere light source with UV and visible light is installed to illuminate the star point hole on the focal plane of reflective collimator to simulate the discharge of infinite target. After receiving by the ultraviolet imager, the star point on the focal plane of the collimator will be imaged as a bright spot on the detector surface of the UV imager. The coincidence degree of the ultraviolet and visible light can be obtained by calculating the center position deviation of the imaging spot in two different spectral ranges. This equipment can be used for high-precision calibration of the non-coincidence of the UV imager.
