Abstract

Real-Time SAHS events detection system during sleep is proposed and investigated based on contact-free Mach-Zehnder Interferometer ballistocardiograph (MZI-BCG) senor, which is placed under the mattress. The breath activity influences the optical phase difference of the MZI which is demodulated with 3∗3 optical coupler. In this paper, three SAHS events are successfully detected, including OSAS (Obstructive sleep apnea syndrome), CSAS (Central sleep apnea syndrome) and MSAS (Mixed sleep apnea syndrome).
