利用薄膜对视觉隐身的研究

A Review of the Application of Thin Films to Visual Stealth

在传统认知中,薄膜属于大部分满足人们日常需求的必备品,不过一旦经过特殊工艺加工,其作用也会在更多领域体现出来。如在用纳米级别的超材料将光弯曲时,外部的观察者可能看不到内部,不过内部也会无法看见外部的视野,此时可以借助各向异性的反隐身层材料,与隐身衣折射率相对立的超材料将光渗透进来,为了使渗透入的光更清晰,还可以增添一层投射膜以增加透射光的光强,从而实现利用薄膜来辅助视觉隐身的效果。

In the traditional cognition,film is the most necessary product to meet people's daily needs,butonce it is processed by special technology,its role will be reflected in more fields.For example,when bendinglight with nano scale metamaterials,the external observer may not see the inside,but the interior will also beunable to see the external field of vision.At this time,with the help of anisotropic anti stealth layer materials,metamaterials opposite to the refractive index of invisibility cloak can penetrate the light.In order to makethe infiltrated light clearer,a projection film can be added to increase the transmitted light So as to realize theeffect of using thin film to assist visual stealth.
