According to the characteristics and the demand of the detection accuracy, an optical detection scheme for monitoring roller condition was proposed and experimentally demonstrated. By analyzing the principle and setting up the mathematical model, a real-time optical detection system is presented in this paper. Moreover error compensation methods of the optical detection part, installation and movement of the detection device, and eccentricity, roundness and rotary movement of the working roller have been adopted in order to ensure the detection process in atrocious condition and to examine roller's shape precisely in real-time. A series of experiments were performed to verify the validity and practical applicability of the detection system. It provides a new method for high speed, accurate and automatic real-time detection for roller condition.
