In this paper we summarize a number of previous experiments on the measurement of the roughness of metallic surfaces by light scattering. We identify several regimes that permit measurement of different surface parameters and functions, and we establ

We have developed a nonlinear model of a commercial optical instrument for measuring the root-mean-square slopes of rough surfaces. The model improves upon previous ones in that it accounts for certain instrumental factors which affect the optical ro

The accurate measurement of surface finish requires standard specimens to calibrate and check the operation of the measuring instruments. This is true both for profiling techniques such as the stylus and area averaging techniques such as light scatte

Angle-resolved light scattering (ARLS) was used to investigate the roughness of coatings on glossy paper. Angular spectra were measured for laser light scattered from several glossy paper samples and from uncoated paper. These spectra are compared to

Surfaces with sinusoidal profiles diffract light, in general, into a number of orders having well-defined intensities and scattering angles. If the diffracted light from such surfaces had seven or eight orders, with intensity dropping by a calculated

The surface roughness of a transparent or translucent dielectric coating can affect the optical appearance of a diffusive surface onto which the coating is applied. Because such coatings are often fragile, it would be useful to have a noncontact, opt

The relationship between the height autocorrelation function of a one-dimensionally rough surface and the Fourier transform of the intensity distribution of the light scattered by that surface is tested experimentally. The theory is derived by using

The application of angle-resolved light scattering (ARLS) to the measurement of the surface roughness of glossy coatings on paper was investigated. To this end, ARLS patterns were measured for laser light scattered from several glossy paper samples,
