本文提出了一种基于光纤干涉仪并结合英国复检测算法的心冲击图（BCG）监测系统。针对光纤干涉仪中信号衰落的问题，提出了一种基于动圈式传感器的相位调制方法，并通过闭环控制器使系统保持正交。结果，可以获得没有基线漂移的稳定BCG信号。基于光纤干涉相位调制法的BCG监测仪具有体积小、成本低、便于携带、使用方便等优点。此外，一个端到端的改进的U-网络进行逐像素分类的BCG信号。该网络可以达到很高的精度，并显示其能力，以部分英国复杂和身体运动的BCG信号。总之，建议BCG监测系统与英国复杂的分割算法是潜在的和有前途的医疗应用。(C)根据OSA开放获取出版协议的条款，2020年美国光学学会
An optical fiber interferometer-based ballistocardiography (BCG) monitoring system aided with the UK complex detection algorithm is proposed in this paper. A new phase modulation method based on a moving-coil transducer is developed to address the problem of signal fading in the optical fiber interferometer and keep the system in quadrature by the closed loop controller. As a result, a stable BCG signal without baseline drift can be obtained. This BCG monitor based on optical fiber interferometer using phase modulation method owns the advantages of compact, low-cost, portable, and user-friendly. In addition, an end-to-end modified U-net is developed to conduct pixel-wise classification in the BCG signal. This network can achieve high accuracy and shows its capability to segment UK complex and body movement in the BCG signal. In conclusion, the proposed BCG monitoring system with UK complex segmentation algorithm is potential and promising in healthcare applications.
