偏振是光的一般描述符，包含传统基于强度的传感器忽略的反射物体的信息。偏振视觉技术使得诸如图像分割和目标定位等困难的计算机视觉任务变得易于处理。如果斯托克斯偏振参数可用，则可以容易地提取镜面反射、遮挡轮廓和材料特性。天体物理学家利用偏振信息来测量太阳表面磁场的空间分布。在医学领域，偏振分析允许诊断眼睛中的疾病。大多数昆虫和某些脊椎动物物种的视网膜对环境中的偏振敏感，但人类对光的这种特性视而不见。生物学家使用偏振计来研究动物在自然栖息地的行为--相对于偏振。在本文中，我们首先介绍了偏振传感的基础知识，然后讨论了我们实验室开发的集成偏振成像传感器。
Polarization is a general descriptor of light and contains information about reflecting objects that traditional intensity-based sensors ignore. Difficult computer vision tasks such as image segmentation and object orientation are made tractable with polarization vision techniques. Specularities, occluding contours, and material properties can be readily extracted if the Stokes polarization parameters are available. Astrophysicists employ polarization information to measure the spatial distribution of magnetic fields on the surface of the sun. In the medical field, analysis of the polarization allows the diagnose of disease in the eyes. The retinae of most insect and certain vertebrate species are sensitive to polarization in their environment, but humans are blind to this property of light. Biologists use polarimeters to investigate behaviors of animals-vis-a-vis polarization-in their natural habitats. In this paper, we first present the basics of polarization sensing and then discuss integrated polarization imaging sensors developed in our laboratory.
