    Abstract: A bipod flexure mount couples an optic to a base while isolating the optic from strain to resist wavefront error. The bipod flexure mount has a distal attachment pad to be coupled to the optic and a proximal attachment pad to be coupled to the base. A pair of beams extend between and couple the distal and proximal attachment pads. The distal attachment pad, the proximal attachment pad and the pair of beams are disposed in and define a planar layer with opposite planar surfaces that are substantially parallel. The bipod flexure mount is relatively flexible about four degrees of freedom and is relatively stiff about two degrees of freedom.

    Abstract: A cardan joint includes a cross-elevation assembly comprising a cross-elevation housing, a roll-elevation assembly comprising a roll-elevation housing, a payload interface assembly comprising a payload interface housing, and a suspension interface yoke comprising a suspension interface that couples the suspension interface yoke to one or more suspension bars. The roll-elevation assembly is rotatably connected to the cross-elevation assembly along a first rotation axis via a radial roller bearing and a thrust roller bearing. The payload interface assembly is rotatably connected to the roll-elevation assembly along a second rotation axis via a radial roller bearing and a thrust roller bearing. The suspension interface yoke is rotatably connected to the cross-elevation assembly along a third rotation axis via one or more radial roller bearings and one or more thrust roller bearings. The payload interface housing comprises a payload interface operable to couple the payload interface housing to an inertially stabilized payload.

    Abstract: A crossbar system for facilitating isolation of a sensor assembly from external vibrations of a support structure. The crossbar system comprises first and second crossbar assemblies and a payload mount, Each of the first and second crossbar assemblies comprises a crossbar segment and a slip plate damper. Each crossbar segment comprises a payload mount interface at a first end of the crossbar assembly and a first support structure interface at a second end of the crossbar assembly. Each slip plate damper is disposed about the crossbar segment and is slidably coupled to the crossbar segment to constrain movement in two lateral degrees of freedom and to facilitate movement in a longitudinal degree of freedom, Each slip plate damper comprises a second support structure interface at the second end of the crossbar assembly. The payload mount is coupled to the payload mount interfaces of the first and second crossbar assemblies.

    Abstract: A relative translation assembly operable with a drive mechanism. The relative translation assembly can have a fixed support member, a translatable member supported by the fixed support member, and a translation guide portion to facilitate translation of the translatable member relative to the fixed support member. The translation guide portion can have a fixed translation member and a movable translation member. The movable translation member can be configured to maintain preload on the fixed and movable translation members and accommodate thermal expansion. The drive mechanism can be configured to cause translation of the translatable member relative to the fixed support member.

    Abstract: A multi-magnification reflective telescope of an optical system includes a case, a shared primary mirror coupled to the case, and a secondary mirror coupled to the case. The shared primary mirror is configured to expand a beam of electromagnetic radiation and the secondary mirror is configured to direct the beam of electromagnetic radiation to and to receive the target image from the shared primary mirror. The multi-magnification reflective telescope is configured to simultaneously direct the beam of electromagnetic radiation along a laser output path toward a target and to receive a target image along an imaging optical path and to direct the target image to one or more detectors simultaneously.

    Abstract: An optical system (e.g., a telescope) comprising an optical assembly that reflects and refracts light rays through a single window about an optical path to a detector. A field-of-view switch assembly comprises a mount, having a pair of diverter mirrors, movably coupled to the optical assembly and being selectively movable between a non-bypass position and a bypass position. The diverter mirrors bypass a first field-of-view and translate a second field-of-view (both through the single window) when moved from the non-bypass position to the bypass position to redirect the optical path. The diverter mirrors straddle the optical path in the non-bypass position. A dynamic shutter shields the second diverter mirror and exposes the second diverter mirror when moved between non-bypass and bypass positions. A four-bar linkage mechanism rotates the mount with an on-board motor and a torsional shaft to absorb impact forces. Associated methods are provided for facilitating switching between fields-of-view.
