An imaging system can include of a plurality of pairs of lenslets and a respective plurality of two-dimensional arrays of photonic waveguides arranged in a respective plurality of photonic integrated circuits. Each waveguide can collect light in an airy-disk-size bin to cover a full field of view of the lenslet. Light from each pair of respective waveguides from each pair of lenslets can be demultiplexed into wavelength bins and combined with appropriate phase shifts to enable a measurement of the complex visibility. The complex visibilities from all of the measurements then can be processed to form an image.

Interferometer array imaging system using photonic integrated circuit cards

An unobscured afocal three-mirror telescope can provide a two-axis gimbal architecture that is more compact, more lightweight, and less expensive than traditional coud&#xe9; path approaches. The telescope can create a real exit pupil and position the exit pupil on a 90-degree fold mirror. Two orthogonal rotational axes can intersect substantially at or about the center of the telescope's exit pupil and on or about the center of the last fold mirror.

Compact articulating telescope

A telescope comprises a folding reflector comprising a plurality of sections configured to fold at a plurality of substantially parallel hinges, a support structure configured to support at least two of the plurality of sections of the folding reflector and further configured to fold at one of the plurality of substantially parallel hinges, a corrector assembly configured to deploy from a stowed position in which an optical axis of the corrector assembly is substantially parallel to the parallel hinges to a deployed position in which the optical axis is substantially perpendicular to the folding reflector when the folding reflector is deployed. The telescope further comprises a hexapod configured to stow and deploy the corrector assembly.

Scanning wide field telescope (SWIFT) spaceflight-deployed payload

A multiple instrument distributed aperture sensor ('MIDAS') science payload system mounted on a spacecraft, including a spacecraft interface ring affixing the MIDAS science payload system to the spacecraft, and a multiple telescope array ('MTA') further including a mechanical subsystem further including an optical bench, an optical subsystem mounted upon the mechanical subsystem collecting light and merging the light into a passive, actively-sensed or hyperspectral image, and a laser subsystem providing laser illumination for collecting active remote sensing data. The MIDAS science payload system also includes a hexapod in physical communication with and between the spacecraft interface ring and the mechanical subsystem. The MIDAS science payload system further includes a plurality of launch locks affixed to the spacecraft interface ring supporting the MTA in a stowed configuration, and a plurality of science instruments (&#x201c;SIs&#x201d;) mounted on the mechanical subsystem obverse to the optical subsystem, individually and concurrently sensing the passive, actively sensed or hyperspectral image.

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.

Fiber optic collimator apparatus and method

A method and apparatus measure the accuracy of and optically calibrate a scan mirror. Both the method and apparatus may operate over a wide range of environmental conditions. The environmental conditions may include variations in pressure from a vacuum to several atmospheres. Similarly, large variations in temperature may be accommodated. The apparatus includes a laser source, a plurality of facet mirrors and a detector. The laser source projects a beam onto a reflective surface of a rotatable scan mirror, which directs the beam to each of the plurality of facet mirrors. Each facet mirror is positioned at a known angle. Each facet mirror in turn reflects the beam from the reflective surface of the scan mirror substantially back onto itself (autocollimation). The angle detector then receives the reflected beam and measures a value related to a return angle of the beam.

Optical metrology device for precision angular measurement of a pointing mirror

A method for deflecting a fluid supply using a skirt. The skirt comprising 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 deflection method 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 method 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.
