摘要
分别将光子晶体薄膜、红外隐身涂层和普通迷彩布作为待测样品贴在60 ℃热源上,并置于室外环境进行红外隐身实验。研究结果表明,太阳光对光子晶体薄膜8~14 μm波段隐身效果影响较小,在绝大部分角度范围内,对3~5 μm波段隐身效果影响也较小;墙壁和大气辐射对光子晶体薄膜3~5 μm和8~14 μm波段隐身效果影响都较小。光子晶体薄膜在中、远红外双波段隐身效果优于另外两种传统红外隐身材料。
Abstract
Photonic crystal (PC), conventional camouflage fabric and infrared stealth coating are used as testing sample, which is attached tightly to a heater with a temperature of 60 ℃ respectively, to perform infrared stealth experiment in outdoor environments. Experimental results show that sunlight affects 8-14 μm waveband stealth effect of PC slightly, while 3-5 μm waveband is also the same in most angle range. Radiation from walls and atmosphere has a little effect on 3-5 μm and 8-14 μm stealth effects of PC. The PC has better infrared stealth performance in both middle and far infrared wavebands, compared with the other two conventional infrared stealth materials.
