| description | This paper presents a new design for an atomic magnetometer for magnetocardiography, which can be easily extended to multi-channel measurements. Virtual instruments are used to demodulate and amplify the photonic signals, enabling signal extraction from input signals with a signal-to-noise ratio of no less than 30 dB. The system based on this design achieves simultaneous demodulation of two-channel signals, with an open-loop sensitivity of 18 fT/Hz1/2 at 17 Hz and a bandwidth of 128 Hz. In open-loop mode, the system successfully measured an analog magnetocardiogram signal with an amplitude of 100 pT, accurately capturing the P-, QRS-, and T-waveforms, offering a novel approach for multi-channel biomagnetic field measurement. |
