| 13. A guided projectile, comprising:
a projectile body;
a guidance controller within the body;
a control surface connected to the body and responsive to the guidance controller; and
an energy detection system, comprising:
an energy detector coupled to the guidance controller, wherein the energy detector is configured to provide signals to the
guidance controller corresponding to a location upon the energy detector receiving a radiant energy; and
an energy concentrator coupled to the energy detector and configured to allow the radiant energy to pass to the energy detector
if the radiant energy enters the energy concentrator within an acceptance angle and reject the radiant energy if the energy
enters the energy concentrator outside the acceptance angle.
