Basing on the principle of laser-linear array CCD detective technology, a high accuracy non-touch on-line optical fibre CCD sensor for monitoring roller wear is brought forward. The principle and composition of the laser-linear array CCD detecting system and the operation process were expatiated. Aiming at the axes shifting of the roller during the detecting process, compensative steps were adopted from the vertical and the parallel detecting surface. And it enhanced the accuracy of the detecting system effectively. Experiments proved that the accuracy of the system could reach to the demand of practical production process. It provides a new method for the high speed, accurate and automatic on line detection of the roller wear.
