Abstract

A method for producing high-resolution images of the polarization information in a scene is presented, and several examples of polarization images are shown. A 35 mm camera with a polarizing filter is used to obtain a set of four slides for each image of interest. The slides are scanned with a digitizing video camera, and the resulting 512 X 512 digital images are manipulated with an image processing computer to produce separate images of the intensity, magnitude of linear polarization, and direction of polarization. Several polarization images of typical natural scenes have been processed by this method. These images show that both the magnitude and direction of polarization contain new and useful information that is not obtainable from the intensi-ty. The Multispectral Resource Sampler (MRS) experimental remote sensing satellite, to be launched in the mid 1980's, will be able to measure both intensity and polarization at several wavelengths. The results of this paper indicate that the additional information obtained from the MRS polarization data should allow previously indistinguishable ground features to be separated.
