1. A system comprising:
a first light source for illuminating an anatomical target via an optical transmission medium;
a second light source, different from the first light source, for generating an output light beam to the anatomical target;
a probe, different from the optical transmission medium, having a first end and a second end, the second end configured to locate adjacent the anatomical target, the probe configured to define a first optical path configured to pass (i) the output light beam from the second light source to the anatomical target and (ii) a reflected signal from the anatomical target in response to the illumination from the first light source;
a beam splitter comprising at least a first port, a second port and a third port, the first port and the second port being configured to define a second optical path, the second port and the third port being configured to define a third optical path to pass at least a portion of the reflected signal;
one or more optical fibers configured to collect at least a portion of the reflected signal; and
an optical sensor system optically coupled to the one or more optical fibers for receiving at least a portion of the reflected signal from the beam splitter, and based at least in part on the received portion of the reflected signal, identifying a characteristic of the anatomical target.
