Method for reconstructing the optical properties of a medium with computing of a signal corrected as a function of a first modeling function for a reference medium and of a second distribution for a medium to be characterized, and associated reconstruction system

A method reconstructing optical properties of a medium, using a reconstruction system comprising at least one radiation source capable of illuminating a medium and at least one detector capable of receiving a signal emitted by the medium,

• the method comprising the following steps:
• establishing, for at least one source-detector pair, a first distribution of a signal received by the corresponding detector for a reference medium, the received signal being emitted by the reference medium subsequent to the illumination of said medium by the corresponding source,
• determining, for said at least one source-detector pair, a first modeling function of a light scattering signal between the source and the detector in the reference medium,
• establishing, for said at least one source-detector pair, a second distribution of a signal received by the corresponding detector for a medium to be characterized, the received signal being emitted by the medium to be characterized subsequent to the illumination of said medium by the corresponding source, and
• computing a corrected signal as a function of the first modeling function;
• and of the second distribution.
