Research progress of visible and infrared adaptive camouflage technology
Adaptive camouflage is an advanced technology that integrates materials science,sensing technology and control engineering.This technology can adjust the detected target in real time according to the changes of the surrounding background environment,so that the optical characteristics of the target in a certain spectral range(such as visible light and infrared)are consistent or close to the background,so as to effectively reduce the detection probability of the target.In recent years,a series of optical control devices and systems based on different control modes have been developed,all of which are play extremely important roles in the field of adaptive camouflage.The research progress of visible light and infrared adaptive camouflage technology was reviewed from four aspects,including light-driven adaptive camouflage,thermal-driven adaptive camouflage,electric-driven adaptive camouflage and intelligent integrated system-driven adaptive camouflage.The control principles and implementation methods of various adaptive camouflage technologies were briefly introduced.Finally,the future development trend of adaptive camouflage technology was discussed,and it was pointed out that the technology was still in the experimental stage,its performance was unstable in the actual environment,and it was difficult to cope with complex background information.Through the research and development of camouflage materials and the establishment of complex background information processing system,the foundation could be laid for the intelligent and diversified development of adaptive camouflage technology.
