The Phase III effort of this research project was directed toward the specification of a practical single-line instrument for the real-time measurement of surface texture from aboard a moving vehicle. Existing instrument concepts were investigated and evaluated, but proved to be inadequate for use aboard a vehicle moving at typical highway speeds. A new instrument concept was devised that showed the potential for use in the moving vehicle application. This concept involves projection of a very short duration, slit of light onto the road surface and detection of the resultant illuminated profile of surface texture with a sensitive vidicon television camera. Analytical and experimental evaluation of this concept verified its feasibility. The preliminary design, performance specifications, and implementation plan for a prototype of this instrument were prepared.
