We have designed an image sensor that can capture the first three Stokes parameters at 648 by 488 spatial resolution at 260 frames per second. The sensor consists of a CCD image sensor monolithically integrated with pixel pitch-matched aluminum nanowire polarization filters. The sensor demonstrates a Malus law response over all pixels, and has a relatively uniform diattenuation over the visible spectrum. We demonstrate two potential applications for the sensor. The first uses circular polarization in transmission mode to observe high-speed stress failure in polycarbonate. The second uses polarization in reflected mode to track high speed automobile traffic.
我们设计了一种图像传感器，它能够以每秒260帧的速度，在648×488的空间分辨率下捕捉前三个斯托克斯参数。该传感器由一个电荷耦合器件（CCD）图像传感器与像素间距匹配的铝纳米线偏振滤波器单片集成而成。该传感器在所有像素上都表现出马吕斯定律响应，并且在可见光谱范围内具有相对均匀的二向色性。我们展示了该传感器的两种潜在应用。第一种应用是在透射模式下使用圆偏振来观察聚碳酸酯中的高速应力破坏。第二种应用是在反射模式下使用偏振来跟踪高速行驶的汽车交通情况。
