Abstract

The polarization of reflected radiation can provide useful information which could be used in remote sensing applications to help distinguish different natural surfaces with similar spectral signatures. Yet the use of polarization has been almost completely neglected in remote sensing applications partially because of the lack of understanding of the information contained in the polarization field. In this paper, examples of the polarization of natural scenes will be presented and the information contained in the polarization field will be discussed. The imagery presented was collected by taking sets of four photographs of various natural scenes using a polarizing filter to detect the polarization field. The polarization field was analyzed by digitizing the photographs and processing the results at the Image Processing Laboratory on the Berkeley campus of the University of California.
