Abstract
A dynamic concentrator system having a concentrator lens, a tracker platform and a receiver. In an embodiment, the concentrator lens is configured to receive an incoming light at an entrance angle α and concentrate the light beam on a focus spot. The tracker platform has a detector optical aperture and one or more actuators. The detector optical aperture can be configured to receive the concentrated light beam. The actuators can move the detector optical aperture in a spatial plane to a location of the focus spot. The receiver has a detector optically coupled to the detector optical aperture to receive the concentrated light beam from the detector optical aperture.

A dynamic concentrator system, comprising:
- a lens configured to receive an incoming light at an entrance angle α and direct the light beam on a focus spot;
- a tracker platform having a detector optical aperture and at least one actuator, the detector optical aperture being configured to receive the light beam and the at least one actuator being configured to move the detector optical aperture in a spatial plane to a center location of the focus spot;
- and
- at least one detector configured to supply a real-time directional feedback signal indicative of a lateral displacement of the focus spot relative to the detector optical aperture,
- wherein the detector optical aperture is moved continuously, during receipt of the light beam, in response to the directional feedback signal to the center location of the focus spot to maintain optical coupling efficiency and compensate for Etendue effect.
