Abstract

We can observe polarization effects in optical sky phenomena by viewing the scene through a polarizing filter. Usually two orthogonal orientations of the filter will provide the greatest difference from polarizing effects. If the scene is photographed through each of these polarizer orientations, the resulting pictures should record much of the polarization information. To observe the polarization effects we can look for the difference in the two photographs. A projection device that emphasizes this difference is demonstrated.
