Infrared Laser Pulse Scattering from Randomly Rough Surfaces
- 33 Downloads
Analytical expression for the two-frequency mutual coherence function of the infrared laser pulse scattering from randomly rough surfaces is presented based on the Kirchhoff approximation. Scattered pulse shapes are calculated at 10.6μm as the Fourier transform of the two-frequency mutual coherent function. It is shown that the root-mean-square height of rough surface greatly influences on results and the scattered pulse power mainly comes from the specular direction with small rms height.
