Classification: CPC A  G  H | IPC A  G  H

Claim 0:
1. An apparatus, comprising:
a probe to interface with a surface of a tissue;
a first light source optically coupled to the probe,
the first light source providing light of up to 900 nm into the tissue;

a second light source optically coupled to the probe,
the second light source providing light of at least 1000 nm into the tissue;

a first detector optically coupled to the probe,
the first detector to detect light scattered in the tissue from the first light source, and
the first detector having a light sensitivity in a range of up to 900 nm;

a second detector optically coupled to the probe,
the second detector to detect light scattered in the tissue from the second light source, and
the second detector having a light sensitivity in a range of at least 1000 nm; and

a processor coupled to the first detector and the second detector, the processor to:
receive a first signal from the first detector corresponding to the detected light from the first light source,
receive a second signal from the second detector corresponding to the detected light from the second light source, and
determine a blood flow measurement from the region of interest based on the first signal and the second signal.
