Only over the past few years have investigations of the intensity distribution of the light reflected from materials been attempted. Most of these investigations have been done by personnel at the National Bureau of Standards on matt surfaces, and acid etched black glass. It should be noted that separate investigations in the two fields, the methods of analysis of a surface\u27s topography and the intensity distribution of reflected light from different materials have been and still are being performed. However, most correlations which exist between a surface\u27s topography and its optical effects such as reflectance, intensity, absorption, and transmission are generally unknown.
The purpose of this investigation is an attempt to correlate the roughness height and the intensity of the light reflected from 99.99% aluminum metal, hereafter simply referred to as aluminum metal, and to try to explain their meaning
