We Sense Differently

Polaris has dedicated years of development to polarization-based imaging systems for military, commercialization, and scientific entities. These systems provide daylight detail in the dark and visibility in low contrast conditions with real-time image processing. Combined with our eTherm® vision enhancement software, Polaris sensors capture, measure, display, and enhance images which can be colorized to display critical data. From concept to prototype to product, Polaris offers custom sensor solutions in any of the visible, near, short, mid, and long wave infrared spectral bands.

The Power of Polarization

The power of polarization is a property of light that offers more information than traditional sensors and details can be extracted from a scene that is not readily apparent in conventional thermal or visible imagers. The polarization signature of certain objects, such as man-made objects or natural substances that differ than the surrounding background, provide additional contrast in polarization imagery. 

Polarization is special because man-made objects generally produce strong polarization signals relative to natural materials. Here some features:

  • IR polarization signals result from preferential emission and reflection of polarized light.
  • The greater the angle of incidence, the greater the polarization signal.
  • The rougher the surface, the smaller the polarization signal.
  • Polarization signal does not depend on temperature difference.
  • Polarization enhances edges due to the abrupt change in surface orientations.

Polarimetric Applications

Polarimetry shows high contrast between oil and the surface of water.

Polarimetry is used to determine heading in GPS-denied environments.

Polarimetry is used to reveal features undetected by standard thermal.
