Method and system for optical data acquisition and tomography imaging of a turbid medium object

A system for tomography imaging of a turbid medium object, the system comprising:

• a variable structured light source, the light source being adapted to illuminate an input surface of the turbid medium object with a plurality of illumination patterns;
• a variable structured light detector, the light detector being adapted to retrieve light from a plurality of detection points of an output surface of the turbid medium object with a plurality of detection patterns, the light detector being further adapted to optically measure a combination of retrieved light from the plurality of detection points as an optical measurement;
• a controller adapted to control the variable structured light source and the variable structured light detector for the variable structured light source and the variable structured light detector to use an illumination pattern corresponding to a detection pattern, the illumination pattern and the corresponding detection pattern being a pattern pair, the controller being further adapted to store an illumination pattern identifier indicative of the illumination pattern, a detection pattern identifier indicative of the detection pattern and the corresponding optical measurement;
• and
• an estimator adapted to determine an optical property based on a reference model, a sensitivity matrix and the optical measurement.

A method for optical data acquisition, the method comprising:

• and
• collecting an optical measurement based on the detected light scattering according to the illumination patterns and the detection patterns.
