Patent ID: 6903813

Claim:
A system for determining optical properties of an object, comprising: a probe tip including one or more light sources and a plurality of light receivers; a first spectrometer system receiving light from a first set of the plurality of light receivers, wherein the first set of the plurality of light receivers is arranged with respect to the one or more light sources so that the first spectrometer system generates data based on light from the object received from a first average optical depth; a second spectrometer system receiving light from a second set of the plurality of light receivers, wherein the second set of the plurality of light receivers is arranged with respect to the one or more light sources so that the second spectrometer system generates data based on light from the object received from a second average optical depth, wherein the second average optical depth is different from the first average optical depth; a processor, wherein the processor receives data generated by the first spectrometer system and the second spectrometer system, wherein optical properties of the object are determined based on data generated by the first and second spectrometer systems.
