Fiber Optic Sensor for Precise Detection of the Moment of Passage of Reflective Labels

This paper analyzes the main factors affecting the accuracy of recording the movement of an object using an amplitude fiber optical sensor with external modulation of the radiation flux is analyzed. The structural scheme, the operating principle and the algorithm for processing the measuring information of a non-contact infrared sensor for recording the moment of passage of a reflective mark are given. The variants of using the developed sensor in the monitoring systems of technological equipment are considered.
