Abstract: A beam control system and method which utilizes the wavefront reversal property of nonlinear optical phase conjugation to permit incorporation of a liquid crystal OPA within the low power legs of the beam control system, thereby affording the advantages of the OPA without the power limitations thereof. The invention is adapted for use with a beacon for illuminating a target with a first beam of electromagnetic energy. The system includes a telescope (1010) for receiving a target return comprising a reflection of the first beam from the target. An optical phased array (1050) is included for correcting for aberrations in the wavefront of the target return. A mechanism is included for ascertaining the correction applied by the optical phased array to the target return. The mechanism applies the correction to a third beam which ultimately is the output beam.

Abstract: Flexible epoxy-based adhesive compositions which remain Theologically stable at room temperature in an uncured state comprise: (a) at least one flexible polyepoxide resin having a hardness not exceeding a durometer Shore D reading of 45 when cured with a stoichiometric amount of diethylene triamine (“DETA”); and (b) a substantially stoichiometric amount of at least one latent epoxy resin curing agent. Optionally, the adhesive composition may also incorporate one or more semi-flexible resins. Other optional components include fillers, thixotropic agents, and flexibilizers. The adhesive composition provicdes an epoxy-based adhesive composition that is storable for weeks as a single component mixture at room temperature, curable at temperatures ranging from about 100° C. to 125° C. in less than two hours, and flexible upon curing to temperatures as low as minus 50° C., exhibiting a durometer Shore A of less than about 95.

Abstract: An image stabilization system and method. The inventive system (100) includes an image sampling circuit (230) mounted on a platform (400) for sampling an image in response to timing control signals and outputting a plurality of imaging signals in response thereto. An azimuth resolver (310) detects vibration of the platform and providing a signal in response thereto. A microprocessor (540) adjusts the timing control signals to cause the image sampling circuit (230) to sample the image and thereby compensate for an effect of vibration on the image. In the illustrative embodiment, the microprocessor (540) includes software for compensating for vibration that causes image offset, compressed images, expanded images, and compression and expansion within a single field. The invention provides image stabilization in a purely electronic manner without the need for any moving parts that would typically require control hardware and a significant amount of space.

Abstract: A system and a method for controlled concurrent viewing of images, in their entirety, by the use of a dual viewer controllable dual display system having the added capability of individually presented resolution is disclosed. In operation, a viewer first selected image is provided by a first controllable display device and a viewer selected second image, typically different from the first, is provided by a second controllable display device. A viewer looks through the second display and sees the image presented by the first display and the image presented by the second display provided at the plane of the first display. Additionally, the displays can be interactive, in that an image or event provided on one display results in the presentation of an image or other data on the other display, all the while allowing the viewer to select from other information. Also the position of one image can be varied with respect to the other image.
