Compensation of the optical fiber sensor based on the surface quality detection for steel balls

This paper introduces the domestic and international steel ball surface defect detection status, a fiber optic sensor with multi-ring receiving fibers was used for the detection of surface defects on steel ball. According to the different mechanism of defects, the different mathematical models were adopted to compensate the displacement-related defects and roughness-related defects on steel ball, so as to achieve the purposes of accurate judgments and distinguish defects.
