光谱选择性激光隐身材料研究现状

摘要

The spectral selective absorbing theory of rare earth upconversion materials,photonic crystals ma terials and organic materials is studied.The upconversion materials can absorb the given wave band lights by the method of upconversion theory,the photonic crystals materials can absorb the given wave band lights by the method of instructive films design and the organic materials can absorb the given wave band lights by the method of functional group vibration.The laser stealth possibility and stealthy methods of those spectral selective absorb ing materials are analyzed,and the study status is also summarized.The spectral selective laser stealth materials are further researches in promoting laser absorptivity,enhancing practicability and compatibility.%综述了稀土上转换、光子晶体和有机体系光谱选择性激光隐身材料的光谱选择吸收机理,稀土上转换材料通过上转换原理、光子晶体材料通过膜系材料结构设计、有机体系材料通过特定官能团振动均可实现特定波段光谱能量的选择性吸收。分析了三种光谱选择吸收材料应用于激光隐身的可行性和激光隐身的实现方式,综述了材料的研究现状。指出,光谱选择性激光隐身材料需在增加激光吸收率、加强材料实用性和兼容性方面进行进一步研究。
