This paper demonstrates the viability of using self-mixing interferometer technique with a customized electro-optic phase modulator to detect the electrocardiographic signals on surface skin. The signals were recorded under two different optical feedback levels where the self-mixing technique operated under strong optical feedback regime was preferred due to the clear advantage of stability and linear relationship between the input and output signal.
