title: Fiber optic temperature sensor using sampled homodyne detection.
abstract: A method of homodyne detection using laser emission frequency modulation and sampling of the interferometer output signal is described for a temperature sensor using a Mach-Zehnder all-fiber interferometer configuration. Both ac and dc signal detection are possible with this scheme. Temperature changes over the 5-80 degrees C range are measurable with a resolution of 1.4 mK by fringe counting and electronically determining the slope of the phase change.
