Abstract: Expanded beams used for object illumination in industrial speckle correlation interferometry are susceptible to noise arising from dirt particles and defects found in the beam expanders. This results in a degeneration of the fringe information. To ensure the integrity of this information, an objective means of monitoring in situ the extent of expander noise is required. In this paper, a practical and cost-effective method based on digital spectral analysis is proposed and demonstrated.
