Optical Magnetometer Employing Adaptive Noise Cancellation For Unshielded Magnetocardiography, Valentina Tiporlini, Kamal Alameh

Research outputs 2013

This paper demonstrates the concept of an optical magnetometer for magnetocardiography. The magnetometer employs a standard Least-Mean-Squares (LMS) algorithm for heart magnetic field measurement within unshielded environment. Experimental results show that the algorithm can extract a weak heart signal from a much-stronger magnetic noise and detect the P, QRS, and T heart features and completely suppress the common power line noise component at 50 Hz.
