摘要： A skirt for deflecting a fluid supply comprises a remote and a close portion (with respect to distance from a fluid impinged surface). The skirt is located in close proximity to a surface to be impinged by the fluid. The skirt is especially suited for use in conjunction with a Joule-Thomson cryostat and can also be used in conjunction with more than one cryostat for cooling of electronic devices. The remote portion of the skirt is disposed around the nozzle or nozzles of the fluid supply so that each fluid supply (or nozzle) extends through a hole in the remote portion of the skirt. The interior surface of the close portion of the skirt extends closer to the fluid impinged surface than each nozzle. The skirt efficiently wets the impinged surface with a fluid providing a measure of control over the outward velocity of the fluid as it progresses along the fluid impinged surface.

摘要： An optical phased array system is disclosed that uses three methods of phased array retargeting: optical retargeting, element slew, and rigid body array slew. These work together in hierarchical fashion to reduce the retargeting disturbances and enhance system performance by shortening retargeting timelines. The optical train configuration given here is an embodiment for the approach to use the rotation of each array element (e.g. telescopes) in the phased array to provide most of the large optical path length shift required for phasing during a phased array look angle shift by individual telescope slew (i.e. venetian blind steering). The optical train configuration discussed here provides about 97% of the optical path length compensation required for a slew to .+-.20 degrees from the array normal. This greatly reduces the amplitude required of the piston control mirror if an equal optical path length is to be maintained from object to sensor. The design geometry is specific to a seven element, one ring array although the concept is applicable to other array configurations.

摘要： Embodiments of the present invention are directed to a compact and stable fiber optic collimator that takes light from one or more optical fibers and generates one or more beams of collimated light at an increased specified diameter. The collimator is configured for easy assembly and for simple and precise adjustment. In one embodiment, a fiber optic collimator comprises a shuttle plug including a cavity for receiving an optical fiber having an optical fiber tip to emit a light through the shuttle plug. A collimator body has a collimator bore to receive the shuttle plug and constrain the shuttle plug in the collimator bore to be movable in an axial direction along an axis of the collimator bore. A collimating lens is mounted to the collimator body and disposed generally opposite from the optical fiber tip to receive a light beam from the optical fiber tip expanding in size toward the collimating lens.
