title: Ultrahigh-sensitivity fiber-optic strain and temperature sensor.
abstract: We report ultrahigh-sensitivity static strain sensing (noise equivalent strain </=1.5n rms) by two fiber etalon cavities made from silica and fluoride fibers. The anomalous thermo-optic coefficient of fluoride glass fibers allows for determination of thermal and laser drift. This sensor is also capable of simultaneous strain and temperature measurement, with errors in strain and temperature of 6.4% and 0.68%, respectively.
