ANGULAR DEPENDENCE OF SURFACE SCATTERED LASER RADIATION.

Abstract

Experiments to determine the relative intensity of light scattered at various angles from several materials were performed. Various target materials were mounted on an optical bench and illuminated by a Spectra Physics 116 gas laser. The targets were rotated through various angles with respect to the optical bench, and the distance between the detector and target was varied to record a constant voltage reading on a 555 oscilloscope. Different graphs showing isointensity lines for various angles of incidence as well as graphs showing the percent of intensity reflected as a function of distance were then plotted. (Author)
