Near-Infrared Fiber Optic Cable:

Functional near-infrared spectroscopy (fNIRS) uses the main components of blood to achieve good scattering of 600-900 NM near-infrared light, thereby obtaining changes in oxyhemoglobin and deoxyhemoglobin during brain activity. At present, the technology is applied to research in many fields such as advanced cognition, development, psychology, and abnormal psychology in a natural context. The technology has low cost, good portability, no noise, no invasiveness, and is The test action is not overly sensitive, but there are also deficiencies in the spatial resolution and the correction algorithm to be further improved.
