Abstract

A novel surface roughness optical fiber sensor is presented. It consists of a light emitting diode source, an Y-tap, a probe made up of self-focusing optical fiber, a photo- detector setup, and a fuzzy system. Its principle is based on the intensity-modulated light from an object surface to be measured. The fuzzy algorithm was used to treat the data obtained from photo-detector setup. Since the fuzzy algorithm can map input and output perfectly, the measure accuracy was improved and the measure range was expanded.
