Compound camouflage of laser and infrared is an urgent demand of modern battlefield,but the requirements of laser and infrared camouflage are contradictory.This problem could be solved by the defect level structure of doped photonic crystals.The reflectance spectrum,transmitted spectrum and absorption spectrum of CdSe/SiO2 photonic crystals thin film doped with ZnSe were calculated by the characteristic matrix method of thin-film optical theory.The result shows that the doped photonic crystals could satisfy the demand of compound camouflage of thermal infrared and 1.06μm or 10.6μm laser.The low reflection of the defect level of doped photonic crystals is caused by the high transmission,which do not satisfy the practice demand of laser camouflage.If the photonic crystals thin film is added with a layer of absorbing substrate,the laser which passes through the defect level will be absorbed.
