摘要

A microprocessor-based noncontact ranging system is discussed, which, along with a computer-based videographics system, constitutes a noncontact texture profiling system developed at the Pennsylvania Transportation Institute. Consisting of a 6502-based single board computer and a Polaroid ultrasonic circuit board, the ranging system is used to monitor the displacement between a traveling test vehicle and the road surface. The texture measurement is performed by the videographic system, which is capable of acquiring data only when it is within a range of plus or minus 1. 2 mm from the pavement.
