Doppler Effect on Back-Scattered Far-Field Intensity for Coherent Light on a Rotating Cylinder.

Abstract

The average intensity and contrast of the back-scattered light from a distant, coherently illuminated, rotating cylinder is examined from a theoretical viewpoint. Although the inclusion of the Doppler effect drastically affects the speckle pattern, it does not significantly alter its statistics for realistic values of target size and angular velocity. Therefore, measurements of average intensity and contrast are practically unaffected. (Author)
