Abstract
The optical device includes a light sensor positioned on a base. The light sensor is configured to receive an input light signal and outputs a passed light signal that includes light from the input light signal. The optical device also includes a return system located on the base. The return system is configured to receive the passed light signal from the light sensor and to return at least a portion of the light from the passed light signal back to the light sensor.
