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.

The Relationship

Focal length of lens is an important parameter to determine the relationship between objective and image. It must be measured accurately. The traditional method of using optical bench to measure the focal length of lens has big man-made errors. So we used linear array CCD camera instead of eyes as the receiver to measure the focal length of lens in this paper. Based on the theory of point spread function, it firstly determined the evaluation function of focal plane. With the threshold method, it determined the location coordinate of sharp signal. Then it proved the feasibility of this scheme through experiment. Finally we compared the experimental data obtained with this method with the experimental data obtained with traditional method, which showed that it was more accurate to measure the focal length of lens with this method.
