Abstract
A fiber optic sensing device for use in a variety of different applications is disclosed. The fiber optic sensing device includes a light source and a first fiber optic waveguide for receiving light from the light source. A second fiber optic waveguide is provided for receiving light from the first fiber optic waveguide. The fiber optic sensing device further includes means mounting the first and second fiber optic waveguides for relative movement to vary the light transmitted between the first and second fiber optic waveguides. A sensor is provided for sensing the light transmitted between the first and second fiber optic waveguides.
