Traditional imaging systems capture and replicate the imaged environment in terms of color and intensity. One important property of light, which the human eye is blind to and is ignored by traditional imaging systems, is polarization. In this paper we present a novel, low power imaging sensor capable of recording the optical properties of partially linearly polarized light in real-time. The imaging sensor combines polymer polarization filters with a CMOS image sensor in order to compute the first three Stokes parameters at the focal plane. The imaging array contains 100 x 100 pixels and consumes 48 mW at 30 fps.
传统成像系统在颜色和强度方面捕捉并复制成像环境。光的一个重要特性是偏振，而人眼对此视而不见，传统成像系统也忽略了这一点。在本文中，我们展示了一种新型的低功耗成像传感器，它能够实时记录部分线偏振光的光学特性。该成像传感器将聚合物偏振滤光片与CMOS图像传感器相结合，以便在焦平面上计算前三个斯托克斯参数。成像阵列包含100×100像素，在30帧每秒的帧率下功耗为48毫瓦。
