    Abstract: A shutter system includes a housing, and a plurality of shutters coupled to the housing. Each of the shutters is rotatable about a respective rotation axis, between a first position and a second position. At least one actuator is attached to the housing, and is coupled to at least one of the shutters for moving that shutter between its respective first position and second position. Each of the shutters define a first angle relative to a reference axis when disposed in their respective first position, and a second angle relative to the reference axis when disposed in their respective second position.
