Abstract

The invention belongs to the technical field of camouflage materials, and particularly relates to a natural vegetation imitating visible light-laser-infrared compatible camouflage film. Comprising a substrate, a thermal infrared dual-band camouflage and near infrared spectrum regulation and control layer and a visible light-laser-near infrared regulation and control layer which are arranged in sequence. The upper-layer natural vegetation imitating structure is mainly used for simulating spectral characteristics of natural vegetation, and meanwhile, the extremely low reflectivity at the position of 1.06 mu m near-infrared laser wavelength is achieved by controlling the thickness of a film layer; the thermal infrared camouflage structure in the middle realizes low emissivity of medium-wave infrared and long-wave infrared; the substrate provides a bearing function. The multilayer film not only can realize refined simulation of a reflection spectrum of natural vegetation in a visible light-near infrared wavelength range, but also has the functions of adjusting different visible light spectrum colors and resisting an infrared detector and a 1.06 [mu] m laser detector; and a visible light-laser-infrared multi-band compatible camouflage performance covering a wide wavelength range of 0.4-14 microns can be realized.
