Fibre-Optic Vibration Probe

A simple, inexpensive Laser Doppler Velocimeter (LDV) is described. The design has been optimised for hand-held machine vibration analysis and incorporates a laser diode and a single-mode optical fibre coupler. The laser diode acts as an integrated frequency-shifting light source and the vibration information is extracted by a pseudo-heterodyne technique.
