Abstract

The camouflage technology requires tailoring the wave characteristics of objects against the possible detections. Currently, there are three essential spectra, i.e. 0.36-0.83 μm visible, 3-5 μm, and 8-14 μm, corresponding to the commonly used visible camera and thermal detectors. To confront these, we here present the efficient design and optimizations of a tri-spectra decoupled thermal emitters using the heterogeneous integrated phase change materials (PCM) multilayer, composed of vanadium dioxide (VO2) and In3SbTe2 (IST). This thermal emitter theoretically can feature both structural colors across the visible range and independently programmable emissivity modulation with up to 80% absolute tuning range in two infrared detection regions. Additionally, two confusing and deceptive colored thermal camouflage methods are proposed based on this thermal emitter, enhancing the camouflage disorientation capabilities and enabling the generation of deceptive infrared images that mimic other objects. This work offers a near-perfect solution with flexible designs for camouflage in complex environments.

异构相变集成多模伪装的三光谱解耦可编程热发射器

这种伪装技术需要根据物体可能被探测到的情况来调整其波动特性。目前有三种基本光谱，即可见光0.36 ~ 0.83 μm、可见光3 ~ 5 μm和可见光8 ~ 14 μm，分别对应于常用的可见光相机和热探测器。为了解决这些问题，我们提出了利用由二氧化钒（VO2）和In3SbTe2 （IST）组成的非均相集成相变材料（PCM）多层材料高效设计和优化三光谱解耦热发射器的方法。理论上，这种热发射器可以在可见光范围内具有结构色和独立可编程的发射率调制，在两个红外探测区域具有高达80%的绝对调谐范围。在此基础上，提出了两种迷惑性和欺骗性彩色热伪装方法，增强了伪装失向能力，实现了模拟其他目标的欺骗性红外图像的生成。这项工作为复杂环境中的伪装提供了一个近乎完美的解决方案，具有灵活的设计。
