Abstract
A sensor may be adapted to reduce motion artifacts by damping the effects of outside forces and sensor motion. A sensor is provided with a motion damping structure adapted to reduce the effect of motion of a sensor emitter and/or detector. Further, a method of damping outside forces and sensor motion is also provided.
