Description

technical field [0001] The invention relates to the technical field of military stealth, in particular to a visible-infrared compatible stealth device. Background technique [0002] Stealth technology (also known as target characteristic signal control technology) is a technology that controls the signal characteristics of the target to make it difficult to be discovered, identified and tracked. Stealth technology refers to detection technology, mainly including visible light stealth, infrared stealth, radar stealth, laser stealth and acoustic stealth. With the continuous advancement of science and technology, various optical and electromagnetic detection technologies have also developed rapidly. The threats to traditional combat weapons have become more and more serious, and have reached the level of "discovery and destruction". requirements, multi-band compatible stealth has become the mainstream. [0003] Visible-infrared compatible stealth means that the material has b...
