Embodiment Construction
[0035] The step (1) of the non-destructive detection of the absolute concentration of oxygenated and reduced hemoglobin includes the following steps in sequence:
[0036] Place the two photoelectric receiving tubes OPUS1, OPUS2 and the light sources LS with 3 emission wavelengths at appropriate positions.
[0037] The step (2) of the non-destructive detection of the absolute concentration of oxygenated and reduced hemoglobin includes the following steps in sequence:
[0038] The microcontroller drives the light source to emit light of three different wavelengths in time, and uses OPUS1 and OPUS2 to measure the corresponding scattered light intensity within 0.5ms in sequence ( image 3 );
[0039] Use the formula of optical density to calculate the optical density at different detection distances :
[0040] OD k λ i = log I 0 ...
