The profilometer in this project uses laser height sensors to measure the distance from the vehicle to the pavements, while some other profilometers use ultra-sonic sensors or broad-band light sensors. Data from the laser sensors is collected by a VMEbus computer running MS-DOS. Software written in the C programming language reduces and processes the collected data into a pavement profile and an International Roughness Index (IRI) value. Additional navigation sensors provide vehicle location information during data acquisition.
