The invention belongs to the field of cerebral blood
oxygen detection, and provides a cerebral blood
oxygen detection
system. The cerebral blood
oxygen detection
system comprises an acquisition module and a
data processing module, wherein the acquisition module comprises N groups of light sources and M groups of detectors, the N groups of the light sources and the M groups of the detectors are arranged on the same side of a to-be-detected sample, and the N groups of the light sources emit at least three kinds of near-
infrared light with different wavelengths into the to-be-detected sample; at least two groups of the detectors in the M groups of the detectors respectively receive near-
infrared light signals which are not absorbed by the to-be-detected sample; and the
data processing module is used for
processing the near-
infrared light signals according to the corrected Lambert-Beer law to obtain cerebral blood oxygen information of the to-be-detected sample. The
system solves the technical problems that in the prior art, when the cerebral blood oxygen information is detected, the light sources and the detectors are arranged on two sides of the to-be-detected sample respectively, an
optical density signal needs to penetrate through the tissue of the to-be-detected sample, the
optical path is long, interference of other chromophores except oxygen-containing
hemoglobin and deoxidized
hemoglobin in the calculation process is large, and the calculation result error is larger.
