  • Patent number: 7116408
    Abstract: Optical properties of an object are determined via light provided to the object via a probe tip including a plurality of light source/light receiver pairs. Light is received from a first light source/light receiver pair, and the first light source/light receiver pair is arranged so that a first measurement generates data based on light from the object received from a first average optical depth or first thickness sensitivity. Light is received from a second light source/light receiver pair, and the second light source/light receiver pair is arranged so that a second measurement generates data based on light from the object received from a second average optical depth or a second thickness sensitivity. The second average optical depth is different from the first average optical depth. Optical properties of the object are determined based on the data generated by the first and second measurements.
