Paper Abstract

A novel instrument based on the Laser-Doppler Velocimetry (LDV) principles has been developed for the in-field detection of torsional oscillations on rotating machinery. The LDV-probe permits the high sensitivity detection of the tangential velocity change on unprepared rough shafts. The probe is realized by means of the micro-optics and all-fiber technology in a compact assembly. E.M. immunity, easy handling and stoutness make the probe suitable for the in-field operation.
