Abstract: A beam-steering apparatus comprises a set of planar tiltable mirrors positioned to define a light beam path therebetween. The set of planar tiltable mirrors comprises from three to five planar tiltable mirrors. Each of the planar tiltable mirrors has a center of rotation lying in a plane of the mirror and each of the planar tiltable mirrors is tiltable about one axis of rotation or two orthogonal axes of rotation that lie in the plane of the mirror. The total number of axes of rotation about which the planar tiltable mirrors of the set of planar tiltable mirrors can tilt is at least five. A mirror drive system tilts each respective planar mirror about its respective axis of rotation or axes of rotation. With this apparatus, an input or output light beam path is steerable over two angular, one rotational, and two lateral-position degrees of freedom.

Abstract: A coude gimbal structure includes a two-axis gimbal system having an outer gimbal pivotable about a first rotational axis, and an inner gimbal supported on the outer gimbal and pivotable about a second rotational axis which intersects the first rotational axis at an intersection point. A folded afocal three-mirror anastigmat has a positive-optical-power primary mirror, a negative-optical-power secondary mirror, and a positive-optical-power tertiary mirror, and a first flat fold mirror, and a second flat fold mirror. A beam path incident upon the primary mirror is reflected from the primary mirror to the secondary mirror. The tertiary mirror lies on the second rotational axis, the first flat fold mirror redirects the beam path reflected from the secondary mirror to the tertiary mirror, and the second flat fold mirror lies at the intersection point and redirects the beam path reflected from the tertiary mirror along the first rotational axis.

Abstract: A two-channel spectrometer has a shared objective and a pair of slits at a common image plane. Each of the slits receives a portion of the output beam of the shared objective and is optimized for transmitting different wavelengths. A shared double-pass reflective triplet receives the output beams of the slits. The output of the reflective triplet is incident upon a beamsplitter, which sends a collimated first reflective triplet output of a first wavelength to a first dispersive element, and a collimated second reflective triplet output of a second wavelength to a second dispersive element. The outputs of the dispersive elements are directed back to the beamsplitter and the reflective triplet to imaging detectors located at two different locations of the common image plane.

Abstract: An imaging spectrometer includes an all-reflective objective module that receives an image input and produces an objective module output at an exit slit, and an all-reflective collimating-and-imaging module that receives the objective module output as an objective-end input and produces a collimating-end output, wherein the collimating-and-imaging module comprises a reflective triplet. A dispersive element receives the collimating-end output and produces a dispersive-end input into the collimating-and-imaging module that is reflected through the collimating-and-imaging module to produce a spectral-image-end output. An imaging detector receives the spectral-image-end output of the collimating-and-imaging module. The objective module may be a three-mirror anastigmat having an integral corrector mirror therein, or an all-reflective, relayed optical system comprising a set of five powered mirrors whose powers sum to substantially zero. The collimating-and-imaging module may be optimized to minimize spectral smile.

Abstract: The present optical system (20) provides an all-reflective vehicle rear vision optical system. A planar mirror (22), acting like a conventional vehicle rearview mirror, would be positioned to receive a beam. The beam would be provided by an image erecting assembly (30) which, in turn, would reflect the beam into a three-mirror anastigmat telescope (24, 26 and 28) to provide rearward image beam to the first planar mirror and in turn, to the exit pupil (25). The optical system provides a 2X magnification at a wide field of view which substantially eliminates blind spots.

Abstract: Illumination, heating and/or damage to baffles (114) and other structures (112) of a telescope (110) during cleaning of its mirrors (116, 118) by a laser beam (128) is avoided by directing the= laser beam from a source (130) outside of the telescope through its entrance aperture (126) and to a reflector (146). The reflector is secured to an already existing telescope shutter (120) so that the beam can be directed on a return path back from the reflector through the entrance aperture and to the outside of the telescope. Preferably, the cleaning occurs by a Nd:GSGG (neodymium and chromium doped gallium garnet crystal) laser (130) after reflection from the reflector. Cleaning is also obtainable by a laser beam generated by a carbon dioxide laser prior to reflection from the reflector.

Abstract: There is disclosed an integrated optical design of head-up displays suitable for use in aircraft cockpits and the like. The display system is comprised of a holographic optical element used as the combiner for presenting a direct view of the exterior on which are superimposed image signals generated by a source device such as a cathode ray tube and transmitted to the combiner through an optical system including a relay lens containing tilted and decentered optical elements to compensate for the aberration present in the holographic optical element. There are further disclosed four relay lens design forms particularly suited for use in the design of such holographic head-up displays. The disclosure includes integrated designs in which (a) the holographic element may or may not be constructed with aberrated wavefront and (b) a beam splitter is incorporated for insertion of a stand-by sight, possibly also being tilted for the correction of aberrations.
