Abstract: An optical assembly includes a primary mirror, a secondary mirror, and an optical steering system configured to support and position the primary mirror and the secondary mirror. The optical steering system includes a base and a yoke rotatably coupled to the base. The yoke is configured to support the primary mirror to rotate the primary mirror about a first axis and to support a secondary mirror to rotate the secondary mirror about a second axis. The yoke further is configured to rotate the primary and secondary mirror about a third axis. The secondary mirror is configured to move from a stowed position in which the optical assembly is positioned to receive an image from a field of view to a deployed position in which the optical assembly is positioned to receive an image from a field of regard.

Abstract: A dual-axis flexure gimbal device, such as for a fast-steering mirror assembly, can comprise a flexure spring mass body comprising first and second body sections, a flexure diaphragm that interconnects the first and second body sections, and a central aperture formed through the first and second body sections and the flexure diaphragm. A flexure unit can be situated in the central aperture, and can comprise a plurality of slots defining a plurality of flexures. The flexure diaphragm is operable to bend about first and second rotational degrees of freedom, and the plurality of flexures of the flexure unit are operable to flex about respective first and second rotational degrees of freedom. The flexure unit can comprise a plurality of slots, each having a first slot portion and a second slot portion extending in different directions to define a respective flexure. A method of making the dual-axis flexure gimbal device is provided.

Abstract: A monolithic gimbal includes a top body portion having a top surface configured to be mounted to a housing, a middle body portion coupled to the top body portion, and a bottom body portion coupled to the middle body portion. The bottom body portion has a bottom surface configured to be mounted to a device. The monolithic gimbal further includes first flexure blades integrally formed with the top body portion and the middle body portion. The first flexure blades enable rotation of the top body portion and the bottom body portion about a first axis. The monolithic gimbal further includes second flexure blades integrally formed with the middle body portion and the bottom body portion. The second flexure blades enable rotation of the top body portion and the bottom body portion about a second axis that is perpendicular to the first axis.
