Extended Experimentation Using Polarization Techniques
Abstract
Polarization can yield image intelligence additional to that accessible from radiometric intensity, wavelength-dependence, texture, topography, or feature shape, size or relative disposition. In this study, investigations were performed to determine to what extent this is true, and to investigate controlling parameters. The objective of this effort was to extend the investigation of the use of polarized light to enhance target-to-background contrast in order to improve target feature detection and discrimination. This study demonstrated, using digital image data collected during 1997 and 1998, that there is great variation in polarization in and between each of the bandpasses, and this variation is comparable to the magnitude of the variation intensity. In addition, it is shown that the contrast in polarization is greater than for intensity, and that polarization contrast increases as intensity contrast decreases. It is also demonstrated that chromaticity can be used to make targets such as camouflage netting stand out more clearly against background. Multiband imaging polarimetry is likely to provide an advantage in feature detection and discrimination.
