Claim One:
1. A method for determining and representing in real time the polarization profile of a scene, comprising: providing four systems having light attenuating optical elements; simultaneously sending rays of light incoming from the scene through all the systems, thereby creating four sets of attenuated rays; passing the sets of attenuated rays through a color filter; passing the sets of attenuated rays to a camera CCD array which forms an image from each of the sets of rays, each of the images having a matrix of pixel values, wherein a given pixel value in one of the images has corresponding pixel values in all others of the images and corresponding sets of pixel values relate to same points in the scene; calibrating a mathematical relation between the pixel values and intensity values; converting the matrices of the pixel values to matrices of the intensity values; using the matrices of intensity values to derive matrices of Stokes parameters S 0 , S 1, S 2, and S 3 ; converting the parameter values S 1, S 2, and S 3 into values for colors unique for each of the parameters by the formula C=int[127.5(1−S)] where C is a color and S is S 1, S 2, or S 3 ; using the unique values to create a color map of the scene which represents the polarization characteristics of the scene.
