Abstract
A novel laser doppler sensor for measuring transverse vibration and angular velocity of rotating cylindrical objects is proposed. The sensor has a sensitivity to only one component of the transverse vibration and it is insensitive to other movements of the object. The optical structure of the sensor is based on two differential type laser doppler velocimeters. The principle of operation of the proposed sensor is theoretically described on the basis of laser doppler anemomentry and the general expressions for vibratory displacement and angular velocity is obtained. The block diagram of the signal processing system is proposed.
