Abstract

The invention provides a testing device for the radiation luminance gain of an ultraviolet image intensifier. The testing device comprises an optical platform and a guide rail arranged on the optical platform, wherein four sliding blocks are arranged on the guide rail, and a light source device, an integrating sphere, a testing dark box and a photometer are arranged on the four sliding blocks in sequence. The light source device emits ultraviolet light, the integrating sphere converts the ultraviolet light into uniform light, the tested image intensifier is arranged in the testing dark box, the uniform light irradiates the cathode surface of the image intensifier, and the photometer measures luminance of a fluorescent screen of the image intensifier; the set heights of the integrating sphere, the testing dark box and the photometer enable light in the testing dark box to be located in a straight line; the tested image intensifier is powered by an external power source. The testing device can detect the radiation luminance gain of the ultraviolet image intensifier, is simple in structure, and has significance on providing technical support for development of a novel detection imaging technology and offering help to the fields of power system detection, the space science and environmental protection research.

Description

technical field [0001] The invention relates to the technical field of performance testing of ultraviolet image intensifiers, in particular to a radiation brightness gain testing device of ultraviolet image intensifiers. Background technique [0002] Ultraviolet (UV) spectral imaging detection technology is a new detection imaging technology developed by European and American countries for military purposes. Its characteristic is to observe and detect "solar-blind" (240-280nm) ultraviolet light signals, and convert ultraviolet image signals into visible light image signals for observation and measurement. Using this technology, many physical, chemical, and biological phenomena that cannot be observed with traditional optical instruments can be observed; and because it works in the "solar blind" band, its work is not disturbed by sunlight, that is, the instrument using this technology can Working under sunlight, the image is clear, reliable and easy to use. Developed countr...
