We're at a hardware disadvantage, but with some practice human beings can also detect light polarization with the naked eye.<p><a href="https://en.wikipedia.org/wiki/Haidinger%27s_brush" rel="nofollow">https://en.wikipedia.org/wiki/Haidinger%27s_brush</a>
This article describes one of several recent camera designs that allow polarized light photography/ videography (see [1]). However Tibbs et al [1] have recently reviewed how in many situations in nature (and in many published field studies),a small amount of noise can create the appearance of polarization where there is none. I look forward to a camera design that incorporates Tibbs et al's suggestions for denoising and decreasing these errors, and that reveals those areas in the picture (if any) where the noise still overwhelms the signal.<p>1 <a href="http://iopscience.iop.org/article/10.1088/1748-3190/aa9e22/pdf" rel="nofollow">http://iopscience.iop.org/article/10.1088/1748-3190/aa9e22/p...</a>
