Fibre-optic vibration probe
Abstract
A practical all-fiber laser vibrometer is described. The design has been optimized for hand-held use and incorporates a frequency-scanned laser diode and a single-mode optical fiber coupler. The vibration information is extracted by a pseudo-heterodyne technique.
