摘要：

We report ultrahigh-sensitivity static strain sensing (noise equivalent strain less than or equal to 1.5 n epsilon 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.
