Abstract

In this paper, we propose a novel calibration procedure based on modeling and measurement of the reflectance distance profiles from a metallic mirror. We observe a remarkable agreement of our reflectance distance profile model with the measurements yielding repeatable calibration factors within 2% when tested on silver and aluminum mirrors. Comparison to widely acceptable calibration using polystyrene microspheres suspensions yields errors of below 10%.
