Abstract: A support system employing a load equalizing floating platform. The support system comprises four jacks 30 including opposed pairs of jacks for coupling to four respective supports. Each jack has a support rod with upper and lower pressure plates attached thereto that are disposed in a cavity to form first, second, third and fourth pressure chambers. Each of the first pressure chambers of all jacks are coupled together. Also, the respective second pressure chambers of jacks are coupled to the opposite jack third pressure chambers. Each of the fourth pressure chambers of all jacks are coupled together. The load equalizing floating platforms equalizes support forces and prevents rotation of the support system due to overturning moments at all support points. The system eliminates stresses and deformations in structures due to unequal support movement. The system may be used to support antenna reflector structures, large telescope mirrors and other structures where support movement or moment loads can degrade performance or function.

Abstract: An active solar reflector, preferably mounted within a transparent dome, tracks the sun from sunrise to sunset to reflect impinging solar radiation into a room or other space to be lighted. The reflector includes a plurality of angled mirrors mounted one behind the other and of progressively increasing heights to intercept and reflect as large a flat plate area of solar radiation as possible. The mirrors are mounted upon a support rotatable about an axis to track the sun and to have the mirrors continuously reflect the impinging solar radiation.

Abstract: A large effective-aperture, low-cost optical telescope with diffraction-limited resolution enables ground-based observation of near-earth space objects. The telescope has a non-redundant, thinned-aperture array in a center-mount, single-structure space frame. It employes speckle interferometric imaging to achieve diffraction-limited resolution. The signal-to-noise ratio problem is mitigated by moving the wavelength of operation to the near-IR, and the image is sensed by a Silicon CCD. The steerable, single-structure array presents a constant pupil. The center-mount, radar-like mount enables low-earth orbit space objects to be tracked as well as increases stiffness of the space frame. In the preferred embodiment, the array has elemental telescopes with subaperture of 2.1 m in a circle-of-nine configuration. The telescope array has an effective aperture of 12 m which provides a diffraction-limited resolution of 0.02 arc seconds. Pathlength matching of the telescope array is maintained by a electro-optical system employing laser metrology. Speckle imaging relaxes pathlength matching tolerance by one order of magnitude as compared to phased arrays. Many features of the telescope contribute to substantial reduction in costs. These include eliminating the conventional protective dome and reducing on-site construction activities. The cost of the telescope scales with the first power of the aperture rather than its third power as in conventional telescopes.

Abstract: 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.

Abstract: An apparatus 30 for kinematically mounting an optic 32, requiring more than three point support, to a structure 38. A holder 34 fixedly contains the optic 32. A ball 44, socket 46 and fastener 50 provide sole support of the optic 32 in three of the six degrees of freedom necessary for complete support. A ball 54, socket 56 and fastener 60 provide sole support of the optic 32 in two of the remaining three degrees of freedom. Two Belleville disc springs 64, a thrust washer 66, thrust bearing 68, one-half ball 70 and fastener 72 support the optic 32 on the structure 38 in the final degree of freedom without introducing redundancy in that final degree of freedom. By providing the capability of having numerous resilient support assemblies supporting the optic 32 in the final degree of freedom without introducing redundancy, heavy optics can be supported with very little structural or thermal distortions.
