Abstract： |
Three light-emitting diodes (LED), each of which can emit light containing two wavelengths, setup at three different locations emit light in sequence in time interval of 0.5ms. Photoelectric detector located at position in same side of the said three LED detects light intensity of diffused from deep tissue irradiated by LED so as to calculate out optical density OD and blood-oxygen saturation of tissue to be tested. Simple structure of the system is suitable to practical request. |
