Abstract
A surgical system includes at least one light emitter generating light at a first intensity and an array of light sensors including a least one row of light sensors, individual light sensors in the row of light sensors adapted to generate a signal including a non-pulsatile component. The system also includes a controller coupled to the array of light sensors, the controller including an analyzer to determine the magnitudes of the non-pulsatile components at the individual light sensors in the row of light sensors, to determine if the non-pulsatile component transitions from a higher magnitude to a lower magnitude and from a lower magnitude to a higher magnitude, and if so, to determine if the first intensity should be changed to a second intensity.
