使用光纤磁强计中的圆柱形直流场偏磁致伸缩换能器，我们演示了在34 kHz附近的70 fT/√(Hz)分辨率。这比以前的结果提高了30db。分辨率受干涉相位噪声的限制，不受上变频低频噪声和残留信号的影响。
Using a cylindrical, DC field biased magnetostrictive transducer in a fibre-optic magnetometer we demonstrate 70 fT/√(Hz) resolution near 34 kHz. This represents 30 dB improvement over previous results. Resolution is limited by interferometric phase noise and is free from upconverted lowfrequency noise and residual signal effects.
