Abstract

Small angle scattering in and near the specular direction has recently been measured with a monostatic laser interferometric reflectometer for a laser beam incident normal to the surface. Employing the Ricean statistics of amplitude distribution for coherent glint with an additive scattered component of speckles, the scattered portion has been partitioned from the total reflected signal at 1.06 and 10.6 micrometers . Such measurements are basic to surface metrology and useful in assessing the performance of mirrors used in lasers and astronomical telescopes.
