Abstract

This paper describes the proposed optical electrocardiograph (ECG) using self-mixing interferometer technique with a customized electro-optic phase modulator as the transducer. The surface ECG signals were recorded using commercially available electrodes demonstrating the feasibility of measuring the ECG signal using the SMI technique with its attendant benefits of intrinsic electrical safety and high level of EMI immunity.
