The most commonly-occurring issue in thermal imagery is that thermal imagery alone is not always enough to distinguish oil from water, a truck from a tree, or to evaluate faces for recognition databases. Our sensors are unique in that they detect an important attribute of light that is often overlooked: polarization. In the scenarios where thermal alone isn’t enough, polarization often is the answer. We have expanded into other realms now including acquisition and tracking and hypersonic aero-optics.
