Abstract
A head for directing radiated energy from a source to a coordinate in a field of view defined by at least one of azimuth and elevation, comprises an angled element and a planar reflecting element. The angled element rotates about a first axis and redirects the beam, the redirection of the angled element differing in at least one of direction and extent as it is rotated. An axis normal to the surface extends at an angle to the second axis. The reflecting surface receives the redirected beam at a point thereon and reflects it in a direction within the FOV. A rotator may be positioned between the source and the angled element to support and independently rotate the angled element and the reflecting surface about the first and second axes without impeding the energy.

38. A head for directing radiated energy from a source to a coordinate in a field of view (FOV) defined by at least one of azimuth and elevation, comprising:
-
a single angled element rotatable about a first axis of rotation, the angled element for redirecting the energy, the redirection differing in at least one of direction and extent as it is rotated; and a planar reflecting surface rotatable about a second axis of rotation, a reflecting axis normal to the reflecting surface being at an angle to the second axis of rotation, the reflecting surface for receiving the energy redirected by the angled element at a point thereon and reflecting it in a direction within the FOV. - View Dependent Claims (39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55)

56. A method of directing radiated energy from a source to a coordinate in a field of view (FOV) defined by at least one of azimuth and elevation, comprising:
-
rotating a single angled element about a first axis of rotation; directing the beam onto the angled element; the angled element redirecting the beam, the redirection of the angled element differing in at least tone of direction and extent as it is rotated; and independently rotating a planar reflecting surface, having a reflecting axis normal to the reflecting surface, about a second axis of rotation that is parallel to the first axis of rotation and at an angle to the reflecting axis; the reflecting surface receiving the energy redirected by the angled element onto a point thereon and reflecting it in a direction within the FOV. - View Dependent Claims (57)
