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: An apparatus includes an optical device that includes a substrate, a first layer of material over the substrate, and a second layer of material comprising an optical coating over the first layer of material. The first layer of material creates a first stress within the optical device that counteracts a second stress within the optical device created by the second layer of material. The optical device may also include a third layer of material positioned between the substrate and the first layer of material. In some cases, the second layer of material creates a compressive stress within the optical device, and the first layer of material creates a tensile stress within the optical device that counteracts the compressive stress within the optical device.

Abstract: An apparatus includes a reflector having one or more reflective faces and an opening. The reflector is selectively movable into and out of an optical path of an alignment beam. When the reflector is located within the optical path of the alignment beam, (i) the one or more reflective faces are configured to reflect a first portion of the alignment beam and (ii) the opening is configured to allow passage of a second portion of the alignment beam through the reflector. The reflector may include a retro-reflector, the retro-reflector may include multiple reflective faces, and the multiple reflective faces may be positioned around the opening.

Abstract: A laser sensor system including a common optical bench that is configured to receive and process different beams of a high energy laser (HEL). The common optical bench is configured to handle the different beams using a modular set of optical components. Optical components of the common optical bench include a filtering device configured to reduce the power of the beams, a common collecting optical element that is configured to set an imaging position and focal length for the beams, a position sensitive detector (PSD) arrangement that is configured to measure angular and positional errors in the beams, and various compaction optical elements, such as mirrors, that are configured to enable compaction of the laser sensor system by increasing the focal length of the beams.

Abstract: An apparatus includes a deformable mirror. The deformable mirror includes a reflective surface configured to reflect a high-energy laser (HEL) beam and to focus the HEL beam on a target. The deformable mirror also includes multiple actuators configured to adjust a shape of the reflective surface in order to maintain focus of the
HEL beam on the target over a specified range of distances between the deformable mirror and the target. At least one portion of the reflective surface is configured to be adjusted by the actuators and obtain convex, flat, and concave shapes.

Abstract: An apparatus includes imaging optics having an objective lens configured to focus electromagnetic radiation to an intermediate image plane and one or more optical devices configured to generate an optical beam from the electromagnetic radiation. The apparatus also includes at least one imaging sensor configured to capture an image from the optical beam. The apparatus further includes a beam generator configured to generate and transmit an HEL beam through the imaging optics. In addition, the apparatus includes an intermediate alignment target configured to be moveably positioned at the intermediate image plane. The intermediate alignment target includes a first-wavelength target configured to reflect a first spectral band of the HEL beam to a first of the at least one imaging sensor (the first imaging sensor configured to capture a first-wavelength infrared image of the first spectral band) and transmit remaining spectral portions of the HEL beam towards the objective lens.
