摘要

空间调制快拍成像测偏技术能通过空间调制将目标全部的斯托克斯参量编码到一幅干涉图像中, 实现一次拍摄获取全部偏振信息和二维空间图像, 在生物医学、空间遥感和军事监测等方面具有重要的科学意义和广阔的应用前景. 在之前的研究中, 理论分析了基于改进型萨瓦偏光镜的空间调制稳态微型快拍成像测偏技术(MSPSIP)方案与基于传统萨瓦偏光镜的空间调制稳态微型快拍成像测偏技术方案相比:前者在空间载频和通道宽度上提高了2倍, 反演目标同一斯托克斯参量的数据面积提高了4倍, 这使得它在空间分辨率和信噪比等方面具有明显优势. 本文采用计算机仿真从定量和定性两方面论证该理论分析的正确性; 采用几何光线模型分析阐明目标的偏振态被MSPSIP调制的详细过程, 并给出了像面干涉图表达式. 搭建了实验装置, 实验验证了该方案的正确性. 讨论了调整分析器偏振化方向对干涉强度的影响, 为MSPSIP的实际应用和优化提供了理论指导. 该技术具有微型轻量、稳态、快拍, 结构简洁、直光路和易配准,可同时获取多维偏振信息和目标图像的显著特点.

Abstract

The spatially modulated snapshot imaging polarimeter can acquire the image and two-dimensional state of polarization using the spatial carrier fringe to encode the full Stokes vectors in a single interference image. It can be used in space exploration, earth observation and detection of biological medicine, land surface and oceans. In an earlier publication, we demonstrated by theoretical analysis that the spatially modulated snapshot imaging polarimeter using modified Savart polariscopes (MSPSIP) is comparable in carrier frequency, signal-to-noise ratio, and spatial resolution to a spatially modulated snapshot imaging polarimeter using conventional Savart polariscopes. In this investigation, the numerical simulation is used to demonstrate theoretical analysis and the feasibility of MSPSIP. Moreover, a geometric ray model is developed to explain the principle and scheme of MSPSIP and derive the expressions of interference intensities. Moreover, a laboratory experiment is conducted to demonstrate the validity of MSPSIP. In addition, we analyze that the interference intensity varies with the direction of polarization analyzer. This investigation enriches the study on MSPSIP and provides a theoretical and practical guidance for study, design, modulation, experiment and engineering of MSPSIP. Furthermore, the MSPSIP operates based on the principle of encodeding polarization information within the spatial modulation of the image. This unique technology allows all Stokes parameters to be simultaneously recorded from each spatial position in an image with a single integration period of the imaging system. The device contains no moving parts and requires no scanning, allowing it to acquire data without the motion artifacts normally associated with scanning polarimeter. In addition to having snapshot imaging and static (no moving parts) capabilities, image processing is simple, and the device is compact, and miniature. Therefore, we believe that MSPSIP will be useful in many applications, such as remote sensing and bioscience.
