摘要
目前的大多数偏振探测系统都遇到了一个共同的问题,即无法在保证偏振探测的时间和空间分辨率的同时具有足够的集成度。为了解决这一问题,在前人偏振探测结构研究的基础上,提出了基于多层结构的仿生偏振探测器,并针对其中主要的偏振敏感超表面仿生结构进行设计。该结构可以模拟昆虫复眼,结合透明感光材料和金属光栅超表面结构构建三层偏振传感结构。通过在532 nm波长下设计优化偏振探测的超表面仿生层,确定了金属厚度为10 nm下超表面仿生层可以获得最优的效果,即消光比为8 d B,并且通过仿真分析验证了其效果。该结构可以同时测量空间中一点入射光的多角度分量信息。通过多点组合检测,该结构还可以实现图形化检测。所设计的新型仿生立体堆叠偏振探测器为未来更先进的偏振检测提供了可行的思路,可以实现更好的偏振检测。
A bionic polarization detector based on multi-layer structure is proposed in this paper,and the polarization sensitive metasurface bionic structure is designed for the main role.The structure can simulate the compound eye of insects and construct a three-layer polarization sensing structure by combining transparent photosensitive material and metal grating metasurface structure.By designing and optimizing the metasurface bionic layer for polarization detection at 532 nm wavelength,it is determined that the metasurface bionic layer with a metal thickness of 10 nm can obtain the best effect,that is,the extinction ratio is 8 dB,and its effect is verified by simulation analysis.The structure can simultaneously measure the multi-angle component information of a single incident light in space.Through multi-point combination detection,the structure can also realize graphical detection.The novel bionic stereo stacked polarization detector designed in this paper provides a feasible idea for more advanced polarization detection in the future,and can achieve better polarization detection.
