Abstract

The invention relates to an infrared-visible composite light source. The infrared-visible composite light source comprises: a black body radiation source and an infrared-visible light composite controller; the output of a heating device and a cooling device of the black-body radiation source is controlled by a temperature controller in the infrared-visible light composite controller Power, adjust the temperature of the radiant plate to adjust the infrared light radiation; through the adjustable voltage source of the infrared-visible light composite controller, adjust the intensity of visible light. The invention mainly provides 1.2 μm-20 μm infrared light and 0.4 μm-0.7 μm visible light, can omit the infrared / visible light recombiner, and has the characteristics of simple structure, low cost, convenient operation and use, 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...
