Resumen:
The autocorrelation function of the intensity scattered from cylindrical rough surfaces is analyticallyobtained with the Kirchhoff scalar diffraction theory.It is shown that, in contrast to the case in whichplanar rough surfaces scatter radiation, this function, related to the speckle size, depends on thestatistical parameters that characterize the surface and on the scattering direction. This result suggests a new, to our knowledge, optical method that can be applied to the characterization of cylindrical rough surfaces, such as in on-line quality assessment, in manufacturing processes.The calculated theoretical expression was tested, showing good agreement with experiments.
