摘要：

A Lorentzian force type fibre-optic magnetic sensor is reported attaining frequency-independent sensitivity in the range 1 Hz to 10 kHz with minimum detectable field down to 50 n T. It is also shown that this technique can introduce frequency superimposition, which enables measurement of AC magnetic fields at different points simultaneously with one interferometer.
