摘　　要：现代探测系统由单一工作模式到复合工作模式的转变,对伪装材料的光谱特性提出了某些特殊要求。作为一种新型人工结构功能材料,光子晶体基于光子禁带的高反射特性可以实现热红外伪装。设计了一种基于一维掺杂光子晶体的远红外与激光兼容伪装材料,利用薄膜光学理论的特征矩阵法计算了透射光谱。制备的样品经测试,与理论曲线相吻合。结果表明,利用一维掺杂光子晶体可以实现远红外与激光兼容伪装。Due to the change of modern detecting systems from the single working mode to the compound workingone, materials with special spectral characteristics are required to meet camouflage demands. As a new kind of man-made structural function material, photonic crystals can realize thermal infrared camouflage because of its high-reflection photon forbidden band. Based on one-dimensional doped photonic crystal, a kind of far infrared and laser band compatible camouflage material is designed, then the transmission spectrum is calculated by characteristic matrix method of thin-film optical theory. The sample of photonic crystal is fabricated. It is found that the actual testing curve is coincident with the theoretic design curve. The result shows that one-dimensional doped photonic crystal can achieve far infrared and laser band compatible camouflage.
