Abstract: An apparatus for the focusing of incident light includes a base assembly that is adapted to support a primary mirror. The primary mirror includes an outside circumference and an inside aperture. An upright member is attached to the base assembly at a first end thereof at a first location that is disposed inside the aperture and at a second location that is disposed outside the primary mirror. The upright member includes a second end that is distally disposed with respect to the first end. The second end is adapted to receive a turret that includes a secondary mirror and is adapted to pivot between two positions. An IMU is attached to the base assembly proximate the primary mirror.

Abstract: An apparatus for enhanced viewing of objects in two separate simultaneous frequency bands of light that is constructed in accordance with the principles of the present invention includes a primary mirror and a moveable secondary mirror that is disposed above the primary mirror to provide a long focal length. A beam splitter splits the optical path into two paths, one for infrared and another path for visible. Various optical elements and devices are described along each path. The secondary mirror is displaced away from its concentric position over the primary mirror to provide shorter focal lengths in IR and visible. Focal Plane Arrays (FPA's) are disposed where desired along both optical paths for real-time viewing and data acquisition. The preferred FPA in visible is a CCD. The preferred FPA in IR is disposed in a Dewar.

Abstract: An apparatus for the control and alignment of a sensor on a moving vehicle is provided that includes a gimbal ball supported by an outer axis structure and adapted to pivot about an outer elevation axis and about an outer azimuth axis. The outer axis structure is mounted to a vehicle. An inner axis structure includes a cardan shaft that is provided in the ball and is used to support a payload. An inner elevation axis passes through the cardan shaft. The payload is moved about inner pitch inner roll and inner yaw axes over a limited range of motion by the use of a plurality of permanent magnet wide-gap motors that are disposed on the plane of the cardan shaft and maximally away from the yaw axis in the ball. The motors are adapted to each urge the payload to move in two perpendicular axes, depending upon the current that is applied through conductors which pass through a flux field. Control circuitry is used to energize the motors in any desired combination to produce motion in roll, pitch, or yaw.
