Abstract: An apparatus for collimating a diagonal mirror. The diagonal has a 45° mirror with adjustment screws for aligning the mirror precisely with the optical axis of the telescope. The mirror is adjacent a back plate attached to the diagonal body. In one embodiment, a resilient pad is between the mirror and a ledge inside the diagonal body. The back plate has a plurality of threaded openings for receiving collimation setscrews that push the mirror at selected points, thereby moving the mirror to be precisely aligned with the optical axis. In another embodiment, the resilient pad is between the mirror and the back plate. The mirror includes a reflective surface and a base, which has threaded openings. The collimation screws pass through the plate, through the pad, and into the threaded openings in the mirror base, and the screws pull the mirror to compress the pad.

Abstract: A link-mechanism base is prepared within a yoke portion, and a link member is prepared in connection with the base within left and right supports. The link member connects the upper part of the supports or the upper part of the yoke portion, and the link-mechanism base. The displacement and angle of rotation of the upper part of the yoke portion are measured by using these link-mechanism base and link member, thereby measuring a change in the pointing direction of a reflector.

Abstract: The invention concerns an optical instrument, designed to be used on a satellite, for simultaneously or quasi-simultaneously observing in two opposite angularly separated directions. It comprises at least two telescopes (TA, TB) having angularly spaced apart observation directions, each having a real and accessible exit pupil and respective planar or superimposable image fields, with a width at least five times more than that of the pupil in a specific direction. Optical means provided at the exit pupil are arranged so as to form the image fields in a common overlapping focal plane except in lateral zones whereof width is substantially equal to that of the exit pupil of the telescopes. In the common focal plane, an assembly of several matrix detectors are arranged and oriented on the superimposition zone of the image fields of the telescopes in the wavefront.

Abstract: An improved structure and method for building large-aperture lightweight deformable mirrors uses a hinged substrate. In addition to reduced weight, the approach provides rigidity to the mirror, which is necessary for the accurate response to actuator commands and tolerance to disturbances. No stresses are induced in the substrate due to the commanded deformation of the substrate, regardless of the magnitude of the deformation. Any stresses in the substrate structure are those induced due to forces in the face sheet, which are likely to be small using advanced nano-laminate and membrane face sheet technologies. The magnitude of the deformation (dynamic range) is limited only by the actuator stroke, and not by the stresses induced in the substrate. The design therefore accommodates small-force, large-stroke actuators, as opposed to the current designs that use large-force, small-stroke actuators. The invention finds utility in numerous applications, including lightweight large aperture mirror substrate and RF reflector structures.

Abstract translation: 用于构建大口径轻量级可变形反射镜的改进的结构和方法使用铰链基板。 除了减轻重量之外，该方法提供了反射镜的刚性，这对于精确响应致动器命令和对干扰的容限是必需的。 由于基板的指令性变形，不管变形的大小如何，在基板中没有引起应力。 衬底结构中的任何应力是由于面板中的力而引起的应力，这可能会使用先进的纳米层压板和膜面片技术而变小。 变形的大小（动态范围）仅由致动器行程限制，而不受由衬底中引起的应力的限制。 因此，该设计适应小力量的大行程致动器，与使用大力量小行程致动器的当前设计相反。 本发明可用于许多应用中，包括轻量级大孔径反射镜基板和RF反射器结构。

Abstract: A prime focus unit that enables position and angle correction within a lens barrel while being located at the prime focus of a telescope. There is provided a first frame on which a barrel top inner tube of a telescope is to be mounted. A second frame is joined to the first frame by way of a Stewart platform comprising six jacks and three pressurized springs. An observation apparatus for collecting observation data and an optical correction system for effecting optical correction are provided on the second frame. If a change arises in the relative position and angle formed between the telescope and the observation apparatus in association with a change in the attitude of the telescope, the change can be eliminated by adjustment of a Stewart platform.

Abstract: An actuator is configured to reliably provide fine and coarse positioning or adjusting for objects such as a telescope or other technical or scientific instrument or communication components, preferably at cryogenic as well as higher temperatures. The actuator includes a fine positioning system and a selectively engageable coarse positioning system. The fine positioning system includes a flexure structure constructed to provide support and strength, preferably in all axes, such as may be needed to withstand launch forces. Preferably flexure axes are defined at upper and lower edges of sidewalls and at intermediate positions of sidewalls. A cam or other suitable device adjusts distance between sidewall intermediate flexures and, by operation of sidewall flexures, adjusts the distance between upper and lower surfaces. A coupling is used to engage or disengage the coarse positioning system from a motor that is also connected to the fine positioning system so that the fine positioning system can perform fine positive or negative adjustments to the coarse position.

A main mirror (1) and an auxiliary mirror (2) are disposed a predetermined distance apart from each other in a face-to-face relation. A main mirror support member (3) and an auxiliary mirror support member (4) serve to support the main mirror (1) and the auxiliary mirror (2), respectively. A plurality of rods (15a) connect the main mirror support member (4) and the auxiliary mirror support member (4) with each other. A plurality of auxiliary rods (15b) are joined at one ends thereof to the main mirror support member (3) or the auxiliary mirror support member (4) and at the other ends thereof to a single connection point (A). A plurality of support legs (26) indirectly support the first and auxiliary mirrors (1), (2) at a total of three points including two points on the main mirror support member (3) and the single connection point (A) at which the auxiliary rods (15b) are joined together.

Abstract: A device such as a secondary mirror of a space telescope is mounted isostatically on a support structure through an integrated compact assembly including three mounting devices, which are preferably identical and uniformly distributed around an axis of symmetry of the device to be supported. Each device is in the form of a deformable triangle in which a first arm materialized by at least a variable length arm is connected to the support structure, and in which the opposite vertex materialized by a support part is connected to the device to be supported. Friction free hinges with zero play connect the arms of the triangle together. Thus the position of the device to be supported can be corrected along six degrees of freedom.

Abstract: A method for making polymeric reflectors and parabolic reflectors in particular. The reflector is made by forming a series of layers (12, 14, 16, 18, and 20) that are progressively thinner with the final polymeric layer (20) being about one millimeter in thickness. The reflector is then coated with a reflective layer (22) by vapor deposition. To make a parabolic reflector, the layers are spun cast at a constant, preselected rate throughout the process, including during the curing of each layer. Layer formation is made in a controlled, particulate-free environment and additives can be used to increase stiffness, decrease weight, and reduce stresses during curing.
