Evaluation of laser profile and deflection measuring system
Abstract
Lasers mounted on a 10-ft beam are used to measure pavement profiles and deflections near a loaded wheel. The lasers require no contact with the pavement surface. The algorithm for solution of the profile is presented along with the solutions for calibrating the system. The system is a promising tool for measuring surface roughness. Continued research is required to improve the system to provide the required accuracy.
