LASER MEASUREMENT OF TORSIONAL VIBRATION: A NEW INSTRUMENT

Traditional methods for monitoring torsional oscillation in rotating machinery components all require contact with the rotating member which necessitates engine 'downtime'. In many cases physical access is very limited, making their use impractical and results are often erroneous. An alternative non-contact method which overcomes some of these disadvantages is the Laser-Doppler Velocimeter. This paper describes the optical geometry of the instrument and discusses its advantages and disadvantages.
