<P>PROBLEM TO BE SOLVED: To provide a highly reliable means for measuring static and dynamic torque from the rotation shaft of a turbomachinery system, and linear and nonlinear vibrations. <P>SOLUTION: An optical splitter 22 based on a multi-branch fiber bundle transmits light to a surface of at least one turbomachinery system shaft 24 with a plurality of optical fiber bundles. The plurality of optical fiber bundles are together arranged substantially axially between ends of at least one shaft 24. The system includes an array of reflective probes 26, 28, 30 and 32 based on a heat-resistant two-branch fiber bundle that receives a reflective signal from the shaft surface, is constituted so as to generate a dynamic reflected light signal, and transmits it to the array of a photosensitivity detector 34. A detecting mechanism 36 calculates the torque or vibration of the turbomachinery system shaft based on the signal processing of time region and frequency region in response to a signature of the dynamic reflected light signal. <P>COPYRIGHT: (C)2010,JPO&INPIT |
