Abstract

The invention discloses a device and method for detecting ultraviolet photoelectronic imaging system performance parameters. The whole detecting device comprises a deuterium lamp light source (1), a light filter wheel (2), an iris diaphragm (3), an integrating sphere (4), an ultraviolet intensity detector (5), an ultraviolet object distinguishability testing target (6), a testing darkroom (7), a main control circuit (11) and a main control computer (16). The main control computer (16) adjusts the light source, the light filter wheel and the iris diaphragm to output ultraviolet light, the ultraviolet light is converted into even area array light through the integrating sphere, and then the ultraviolet light irradiates an ultraviolet photoelectronic imaging system (10) to be tested in the testing darkroom. The main control circuit carries out noise reduction, collecting and analog-digital conversion on output signals of the ultraviolet photoelectronic imaging system to be tested, and then the output signals are sent to the main control computer. The main control computer computes obtained data, and the performance parameters of the ultraviolet photoelectronic imaging system to be tested are obtained. An optical environment which can change accurately is provided for the tested ultraviolet photoelectronic imaging system, testing stability is high, and the device and method are suitable for detecting the performance parameters of all ultraviolet photoelectronic imaging systems.

Description
