Research output: Contribution to journalArticlepeer-review


We report an imaging sensor capable of recording the optical properties of partially polarized light by monolithically integrating aluminum nanowire optical filters with a CCD imaging array. The imaging sensor, composed of 1000 by 1000 imaging elements with 7.4μm pixel pitch, is covered with an array of pixel-pitch matched nanowire optical filters with four different orientations offset by 45°. The polarization imaging sensor has a signal-to-noise ratio of 45dB and captures intensity, angle and degree of linear polarization in the visible spectrum at 40 frames per second with 300mW of power consumption.
