We present a full Stokes imaging polarimeter using a rotating retarder in combination with a polarization camera-a detector array on which a pixelated polarizer array is attached. By itself, a polarization camera cannot capture the full Stokes parameters, but we add a rotating retarder in front and show how it can be used to provide full Stokes images. In addition, we demonstrate the advantage that it can be recalibrated dynamically while taking measurements, allowing accurate measurements even in environments where the retardance in changing.
我们展示了一种全斯托克斯成像偏振计，它使用旋转延迟器与偏振相机相结合——偏振相机是一种附有像素化偏振器阵列的探测器阵列。偏振相机本身无法捕捉完整的斯托克斯参数，但我们在其前面添加了一个旋转延迟器，并展示了如何使用它来提供全斯托克斯图像。此外，我们还展示了该偏振计的优势，即在进行测量时它可以动态重新校准，即使在延迟发生变化的环境中也能进行精确测量。
