The wavelength shifting fibers provide an efficient method for capturing photons of light that strike them. Photons may strike the fibers as they first pass through a clear lens in the shroud or may strike the fibers after they are concentrated and focused by an embedded ring or hyperbolic mirror. The wireless optical receiver may be attached to a mobile vehicle in order to facilitate teleoperation of that vehicle.
