34. A device for optically measuring a characteristic of at least one of a blood vessel and blood flowing through the blood vessel, the device including:
-
a housing having a first side and a second side; a sensor assembly mounted to the housing and including a plurality of emitters for emitting photons through the first side of the housing and a plurality of detectors for receiving at least a portion of the emitted photons though the first side of the housing, each emitter being operationally paired with a separate detector and oriented such that a beam of photons emitted from the emitter that impinges upon a vessel adjacent the sensor assembly will partially reflect toward the paired detector, each detector being configured to produce a signal representing the emitted photons received by the detector; a computing device configured to activate the plurality of emitters and interpret the signals from the detectors to determine the characteristic. - View Dependent Claims (35, 36, 37, 38, 39)
