ABSTRACT:
Curved thermal objects emit infrared energy with different ratios of ordiy-to-extraordinary polarizations compared to flat thermal objects. The invention takes advantage of this by taking the sum or difference of or between thermal images for two different polarization images of a scene. The curved objects are enhanced with respect to the remainder of the scene on a viewer.
