Abstract
Power savings occur when the optical path of an optical navigation device is configured to provide that maximum energy from the light source is reflected by the navigation surface to the photosensors of the optical navigation chip. Additional power savings may be achieved when the maximized optical path is combined with the features of a controlled light source that uses specular reflection.
