SYSTEM AND METHOD FOR IMPROVING THE SIGNAL-TO-NOISE RATIO FOR REFLECTIVE-BASED SENSORS

The present disclosure provides systems and methods for improving signal-to-noise ratio (SNR) for a medical device sensor operating in reflective mode such that light from an emitter travels through tissue via reflection to a first detector at a first depth to provide a first detected signal over time and such that light from the emitter travels through tissue via reflection to a second detector at a second, greater depth to provide a second detected signal over time, with subtracting out the signal from superficial tissue that is common to the first and the second detected signals to provide an improved signal-to-noise ratio for the medical device sensor.
