Abstract
Plastic mines are cheap, small, and difficult to detect using current methods. IR polarization discrimination where the mines present themselves as a flashing signal may be of potential benefit in finding surface laid or scattered types in a cluttered background. Results from a laboratory study show that plastic has significant 8-14 micrometers IR polarization in emission and reflection. We have constructed a 10.6 micrometers ellipsometer which has been used to measure the complex refractive indices of mine-like plastics. This apparatus was then modified to determine the degree of emission polarization. The measured degree of emission polarization has been compared to that predicted using the complex refractive index and good agreement found.
