Optics.org: Polaris Sensor Technologies claims that polarized thermal imaging can offer so much more. David Chenault, the company president, says that their thermal camera with sensitivity to the light polarization, eTherm, is better at seeing at night, better at spotting a potential intruder behind a bush, or to see camouflaged targets. An extra advantage, is that it does not require temperature differences to create an image. "We can form the image from the material itself, from its texture and shape," says Chenault.
