Abstract

A novel fibre-optic laser vibrometer has been developed in which a single highly birefringent fibre links the launch optics with a simple passive all-glass instrument head. The instrument utilises heterodyne detection and can be made insensitive to undesired vibration effects acting on the fibre. The instrument may be greatly simplified and its performance enhanced if it is realised in all-fibre form.
