Abstract

An infrared detector responsivity testing device comprises an optical testing platform, a three-dimensional displacement table which is arranged on the optical testing platform and can move in an X direction, a Y direction and a Z direction, a black bracket which is fixed to one end of the optical testing platform, a light source system and a testing processing system. The light source system is mounted on the black bracket and comprises a black member, a diaphragm, an optical filter and a black member controller. The three-dimensional displacement table is provided with a tested detector. The testing processing system comprises a test computer and a test board. The test computer is in signal connection with the black member controller for controlling radiation temperature of the black member. A radiation signal which is transmitted from the black member is vertically irradiated to the tested detector through the diaphragm and the optical filter. The tested detector is in signal connection with the test board. The test board is electrically connected with the test computer. The test computer acquires various items of testing data on the test board. The infrared detector responsivity testing device has advantages of simple operation, high practicability, relatively high test precision and high suitability for popularization.

Description

technical field [0001] The invention relates to a detection technology of a photoelectric detector, in particular to a device for measuring the responsivity of an infrared detector. Background technique [0002] In recent years, with the rapid development of my country's aerospace industry, industrial and agricultural production, and science and technology, infrared detector technology has been more and more widely used in different fields. In addition to the advantages of small size, light weight, and the ability to identify invisible light, the infrared detector also has a high detection rate, basically no limit to the wavelength, can be used normally at room temperature, and has a relatively reliable structure. Therefore, it has been widely used in the fields of aerospace, national defense construction, industrial and agricultural production, transportation and scientific research systems. In order to obtain data with high accuracy and reliability, higher and higher requ...
