Laser Doppler Velocimetry of Rotating Cylinder with Retroreflecting Surface


Gregory Dolya, Kostiantyn Bondarenko

Abstract


A method for measuring rotation frequency of cylindrical object is considered, taking into account features of retroreflecting surface based on micro glass beads. Method involves single-beam object probing, detection of scattered radiation and spectral analysis of the recorded photocurrent. A mathematical model of the proposed method is described. Results of physical simulation are presented in form of plots, showing dependencies of received signal power on the frequency. Analysis of changes in registered photocurrent spectrum was done, taking into account both changes due to the vary of angular velocity of cylinder and those caused by rotation axis displacement in regard of falling light beam.
