可穿戴式的功能近红外光谱成像系统的前端设计
The front-end design of wearable functional near-infrared spectroscopy system
摘要
Abstract
A wearable multi-channel functional near-infrared spectroscopy (fNIRS) imaging system front-end is designed, which can monitor brain blood oxygen in non-invasive and non-destructive condition. In order to achieve a front-end of brain imaging system with small size, low power consumption, high precision, wireless transmission and real-timely acquisition, ultra-low power wireless system on chip (SoC) is used as the control center and wireless transmission module, adopting time division multiplexing technology to drive light source, and implementing data acquisition by using high sensitivity photoelectric sensor and high resolution A/D chip. At the end of this paper, the method of extending the light source driving and signal acquisition are given, which allows the system to be freely expanded to more channel acquisition system.关键词
