Near-infrared spectroscopy technology can achieve non-invasive, real-time, continuous monitoring of tissue oxygenation parameters, providing a basis for clinical monitoring, treatment and evaluation, and is a hot spot for sustainable development in the field of biomedical optics applications.
In 1994, the research group led by Professor Ding Haishu of Tsinghua University School of Medicine undertook the research task of non-destructive monitoring of tissue blood oxygen content by near infrared spectroscopy.
