Super- and Sub-Specular Maxima in the Angular Distribution of Polarized Radiation Reflected from Roughened Dielectric Surfaces
Abstract
To study the effects of surface roughness on the reflection of radiation from the vacuum-deposit interface of CO2 cryodeposits, detailed angular distribution measurements were made of the polarized radiant flux reflected from roughened glass samples which had similar optical properties to CO2 cryodeposits. As a result of these measurements, a new type of off-specular peak was discovered. A formula is derived for the radiation reflected in the plane of incidence and is used to quantitatively confirm the existence of the super- and sub-specular maxima for moderate incidence angles. The super- and sub-specular maxima phenomena have potential application to making in situ measurements of surface roughness characteristics.
