Nano-fabricated pixelated micropolarizer array for visible imaging polarimetry
Z Zhang, F Dong, T Cheng, K Qiu, Q Zhang… - Review of scientific …, 2014 - pubs.aip.org
Pixelated micropolarizer array (PMA) is a novel concept for real-time visible imaging
polarimetry. A 320× 240 aluminum PMA fabricated by electron beam lithography is
described in this paper. The period, duty ratio, and depth of the grating are 140 nm, 0.5, and
100 nm, respectively. The units are standard square structures and the metal nanowires of
the grating are collimating and uniformly thick. The extinction ratio of 75 and the maximum
polarization transmittance of 78.8% demonstrate that the PMA is suitable for polarization …
