大多数成像偏振仪只测量米勒矩阵的几个分量或它们的组合，如斯托克斯矢量、线偏振度(DOLP)和圆偏振度(DOCP)。我们的成像偏振仪是相似的，因为它产生了16个穆勒分量的两种组合。我们升级了我们的偏振仪，以获取现场场景的米勒矩阵(米勒图像)。场景包括安装在一个大面板上的平板，一个大圆柱体，以及树木和草地等自然背景。我们建立了一个公式，从我们的仪器测量得到穆勒图像。Mueller图像提供了关于场景中任何目标的偏振效应的全面信息，这对于区分人造目标和自然背景很有用。此外，米勒图像使我们能够通过成像能力有限的偏振仪来模拟一些图像。将这些图像与Mueller图像进行比较，可以深入了解相关成像偏振仪的有效性和缺点。
Most of imaging polarimeters in the field measure only a few components of the Mueller matrix or their combinations such as Stokes vector, degree of linear polarization (DOLP) and degree of circular polarization (DOCP). Our imaging polarimeter was similar in that it produced two combinations of 16 Mueller components. We upgraded our polarimeter to acquire the Mueller matrix of a scene in the field (Mueller image). Scenes consisted of flat plates mounted on a large panel, a large cylinder, and natural background such as trees and grass. We established a formula to derive Mueller images from the measurements with our instrument. Mueller images provided comprehensive information about the polarization effect on any targets in the scene, which were useful in distinguishing man-made objects from natural background. In addition, Mueller images enabled us to emulate some images by imaging polarimeters with limited capability. Comparison of those images with Mueller images provided an insight on the effectiveness and shortcomings of the associated imaging polarimeters.
