Abstract: A detector assembly (300, 500) includes a dewar chamber (102, 502) having an aperture (108, 510) and an infrared radiation detector (106, 514). The detector assembly also includes a mirror (304, 400, 410, 504) disposed adjacent the aperture of the dewar chamber, where the mirror has a reflective surface (306, 604) and an emitting region (305, 402, 412, 606) facing the aperture. The infrared radiation detector is configured to detect first radiation and second radiation from the mirror. The first radiation originates from at least one relatively cold surface in the dewar chamber and reflects off the reflective surface of the mirror. The second warm radiation originates from at least one relatively warm surface at or behind the emitting region. The infrared radiation detector is also configured to detect an artifact (122, 712, 722, 802) caused by a particle (110) in the dewar chamber that blocks a portion of the first or second radiation.

Abstract: Asymmetric rotating stray light baffles are provided for conformal dome two-axis seekers having arch corrector optics mounted on the outer gimbal. A pair of side skirt baffles are mounted on opposite sides of the arch corrector optics on the outer gimbal extending forward beyond the transparent arch adjacent but not touching the inner surface of the dome and extending aft beyond the forward most receiver optic for all fields of regard (FOR). The optical system may also include: (a) an annular objective baffle mounted on and around the receiver optics on the inner gimbal and between the pair of side skirt baffles, the objective baffle extending forward of the receiver optics without interfering with the receiver optics' FOV and without interfering with the transparent arch as the inner gimbal rotates, (b) a plurality of fin baffles mounted between the side skirt baffles on the outer gimbal that extend forward adjacent but not touching the inner surface of the dome and aft of the transparent arch, each fin baffle positioned to reduce the cross-section seen by the receiver optic when rotated in the direction of that fin baffle and (c) central baffles (short or long) along the axis of symmetry that obscure a portion of the receiver optics' FOV at a zero degree angle of rotation about the second axis.

Abstract: A mount between an optical element (22) and a housing (24) includes an optical element that has an optical element mount (26) with plural optical element mounting pads (28) and an optical element connecting surface (30) that links the optical element mounting pads together. The housing includes a housing mount that has plural housing mounting pads and a housing connecting surface that links the housing mounting pads together. The optical element mount and the housing mount are mounted to one another such that the only contact between the optical element and the housing is between the mounting pads of each respective element.
