Paper Abstract

When light irradiates to a test part, the change of the position of the test part can make the intensity of the reflecting light alter accordingly, based on this mechanism of reflective light intensity modulation, a new scheme with optical-fiber displacement sensor is put forward to testing the tip clearance of labyrinth seals. By analysis and treatment of the data from calibration test in static condition, the relationship of the optical-fiber displacement sensor's output in static state and the position from the test part to the sensor are obtained, also influence of different environments to the response curves is analyzed. The results of the experiment show that the presented scheme is feasible, and the high measuring accuracy of the optical-fiber sensor can meet the prospective purpose.
