摘要：
A flux transformer is magnetically coupled to a SQUID (112), and a plurality of SQUIDs (114B1 115B, 116B, 117B), connected in series, is magnetically coupled to the output of the SQUID. Alternatively, a flux transformer (108, 110) and a modulating coil (330) are magnetically coupled to a SQUID and an oscillator drives the modulating coil (230) at a frequency f. A processing system (306) mixes the output signal of the SQUID with sin(wt) and cos(2wt), where w = 2TT.f.
