Abstract
This paper discussed the presence of `laser noise' in velocity measurements taken with an SLDV system. In this paper, an experiment is presented to investigate the optimal operating range of velocities for the SLDV system. Additionally, an experiment investigating the effect of the use of a highly retroreflective surface treatment on `laser noise' is also presented. In order to determine the relative extent of the `laser noise' in these scans, a novel statistical value which quantifies the overall quality of the scan data is developed, presented, and exercised on experimental test data.
