Abstract : "A simple procedure for generating photographs is reported showing polarizing effects of reflecting surfaces from the photos taken with a photographic camera with a polarizer and also from the digital output of radiometer with a polarizer. Photos generated by displaying the degree of polarization (DOP) of light reflected from the surfaces of objects at each point in both cases have provided higher inherent visual contrast, revealing details which are not available in intensity images of remotely sensed data. DOP image is expected to provide additional invaluable supplementary information of defence interest, which is otherwise not available. Possible applications and limitations of the procedure are discussed. "
