A 1300 × 800, 700 mW, 30 fps spectral polarization imager

We have designed, fabricated, and tested a division-of-focal-plane polarimeter capable of simultaneously imaging both spectral and polarization information at 30 frames per second. The imaging sensor, composed of 1300 by 800 imaging elements, each containing three vertically stacked photodetectors,...

Summary:We have designed, fabricated, and tested a division-of-focal-plane polarimeter capable of simultaneously imaging both spectral and polarization information at 30 frames per second. The imaging sensor, composed of 1300 by 800 imaging elements, each containing three vertically stacked photodetectors, is covered by pixelated nanowire polarization filters at four different orientations offset by 45°. The polarimeter has a dynamic range of 62 dB and captures intensity, angle, and degree of linear polarization in three visible spectrum bands while consuming 700 mW of power.
