Abstract

The invention relates to an infrared-visible composite light source comprising a blackbody radiation source and an infrared-visible light composite controller. The output power of a heating device and a refrigerating device of the blackbody radiation source is controlled by a temperature control instrument in the infrared-visible light composite controller. The temperature of a radiation plate is adjusted to adjust infrared light radiation. The intensity of visible light is adjusted by an adjustable voltage source in the infrared-visible light composite controller. The infrared-visible composite light source of the invention mainly provides infrared light from 1.2 microns to 20 microns and visible light from 0.4 microns to 0.7 microns. An infrared / visible light compositor can be omitted. The infrared-visible composite light source has the characteristics of simple structure, low cost, convenient use and operation, and the like.

Description

technical field [0001] The invention relates to the technical field of multi-mode imager calibration and testing, in particular to an infrared-visible composite light source. Background technique [0002] With the development of technology, the application of infrared and visible light imagers has been extended to near space and outer space. system etc. During the development, production, and test of these infrared systems, it is necessary to use infrared / visible composite light sources to perform precise radiation calibration and performance tests on the imager in the ground environment according to the working environment of the system, so as to obtain accurate calibration coefficients and accurate Master the performance indicators of the imaging system to ensure that its performance indicators reach the pre-designed values. [0003] The remote sensing data sent back by the visible light / infrared fusion remote sensing detector carried on the space vehicle is an electrica...
