Light scattering from cold rolled aluminum surfaces

TL;DR

This paper reports experimental light scattering measurements from cold rolled aluminum surfaces, demonstrating that the surface roughness can be described by a scale-invariant model consistent with AFM measurements.

Contribution

It introduces a scale-invariant approach to characterize surface roughness using light scattering, validated by AFM data.

Findings

Light scattering results align with scale-invariant roughness model

Roughness parameters from scattering match AFM measurements

Surface roughness characterized effectively through optical methods

Abstract

We present experimental light scattering measurements from aluminum surfaces obtained by cold rolling. We show that our results are consistent with a scale invariant description of the roughness of these surfaces. The roughness parameters that we obtain from the light scattering experiment are consistent with those obtained from Atomic Force Microscopy measurements.
