SYSTEME DE RECONSTRUCTION DE PROPRIETES OPTIQUES D'UN MILIEU DIFFUSANT, COMPRENANT UNE SOURCE DE RAYONNEMENT PULSEE ET AU MOINS DEUX DETECTEURS DE DEUX TYPES DIFFERENTS, ET PROCEDE DE RECONSTRUCTION ASSOCIE

摘要

The system (10) has a detector (16) receiving a signal emitted by a diffusing medium (12) upon illumination by a pulsed radiation source (14). A processing unit processes time distribution of a signal for a source-detector pair. Another detector (22) measures signal intensity corresponding to equivalent moment of order 0 for a source-latter detector pair. A computing unit (62) computes a base parameter by combining characteristic magnitude of the distribution with intensity measured for the source-latter detector pair and reconstructs optical properties from the parameter. The detector is formed of set of pixels from an image sensor (18) e.g. charge-coupled device (CCD) sensor or a complementary metal oxide semiconductor (CMOS) sensor. The detectors are respectively time resolved detector and non-time-resolved detector. An independent claim is also included for a method for reconstructing optical properties of a diffusing medium.
