A linear interferometric sensor system in which the light output from the interferometric sensor is optically bandpass filtered before conversion to an electrical signal by an adjustable band-pass filtering device and the center wavelength of the adjustable band-pass filtering device is controlled by a feedback circuit responsive to the steady state component of the electrical signal corresponding to the filtered sensor return. In a preferred embodiment, the adjustable band-pass filtering device is an electrically tunable optical filter. The invention is particularly useful in self calibrating interferometric/intensity-based sensor configuration, but can be used with other linear interferometric sensor configurations.

An optical waveguide includes a sapphire body having thereon a cladding containing spinel.

Cladding for high temperature optical component and method of making same

A fiber optic system and method of use is disclosed. The fiber optic system comprises a laminated, pre-stressed, piezoelectric actuator; and a fiber optic strain gage having an input/output fiber, wherein the fiber optic strain gage is attached to a surface of the laminated, pre-stressed, piezoelectric actuator. The fiber optic system is useful for performing dynamic mechanical analysis on a sample.
