微偏振阵列是分焦平面偏振计的核心元件。相较于纳米线栅阵列,液晶偏振阵列有着设计灵活、工艺简便、性能稳定等独特优势,有望实现高性价比、高精准度的偏振测量与成像。本文综述了近年来国内外科研团队针对液晶微偏振阵列展开的研究,系统阐述了基于宾主型、偏振旋转型和相位延迟型3大类液晶偏振阵列的器件结构和工作原理,不同的液晶排列结构可以实现从单一线偏振到全Stokes矢量的测量和成像,最后讨论了液晶微偏振阵列与偏振探测技术相结合的发展趋势和应用中面临的挑战。
Micropolarizer array (MPA) is the core component of division of focal plane polarimeter (DoFP). Compared with nano-wire-grid polarizer array
liquid crystal micropolarizer (LCMP) array has some unique advantages such as flexible design
simple process
good stability and show great potential to achieve not only cost-effective but also high precision polarization measurement and imaging. In this paper
we summarize the researches on LCMP array domestic and oversea in recent years. Here
three working principle of LCMP arrays: guest-host effect
polarization rotation and phase retardation as well as their structure are systematically elaborated. Different alignment structures of LCMP can achieve not only linear but full Stokes polarimetry. Finally
future development trends and key challenges of liquid crystal micropolarizer arrays and DoFP imaging technology are discussed.
