Abstract:
1. Process for the measurement of the level of a tissue constituent, characterized in that is/are measured a first light reflection with a first given wavelength that is representative of the measurement to be performed and at least a second measurement of the light reflection for another second predetermined wavelength that will serve as a reference unit value Rf, by calculating the coefficient k between the reflection measured on the tissue for this second wavelength and the reflection measured on a standard for this same second wavelength, and in that the level of the constituent to be evaluated is deduced from the measurement of the reflection of the first wavelength according to a table of predetermined values known for this same first wavelength, after correction by the factor k previously measured of said reflection measurement, so as to obtain the value to be compared to the table reference values, said unit value and said second wavelength determining a point through which will go all the LIR curves after standardization.
