  • Abstract
  • Look Inside

The near infrared (NIR) light can penetrate the human body. So, as the technology of photodetection system develops, it has been able to be used for the examination of the internal human body. The NIR light is absorbed mainly by oxygenated hemoglobin (oxy-Hb), deoxygenated hemoglobin (deoxy-Hb) , oxygenated cytochrom-aa3 (Cyt), and deoxygenated cytochrorn-aa3 (Cyt-H) in the brain tissue. By using four NIR lights, a NIR spectrometer can measure the amount of oxy-Hb and deoxy-Hb theoreti-cally.
