摘要： The disclosed technology provides a dynamic interconnection system which allows to couple a pair of optical beams carrying modulation information. In accordance with the disclosed technology, two optical beams emanate from transceivers at two different locations. Each beam may not see the other beam point of origin (non-line-of-sight link), but both beams can see a third platform that contains the system of the disclosed technology. Each beam incident on the interconnection system is directed into the reverse direction of the other, so that each transceiver will detect the beam which emanated from the other transceiver. The system dynamically compensates for propagation distortions preferably using closed-loop optical devices, while preserving the information encoded on each beam.

摘要： Optical devices are disclosed which rely upon Stark-induced resonant, tunable, and saturable birefringence and dichroism to provide both digital and linear amplitude optical modulators, optical shutters, tunable optical filters, and optical cutoff limiters. A Stark cell is disposed along a light beam path between two crossed polarizers with its electric field direction at 45.degree. to the polarizer pass directions. The Stark cell contains a medium exhibiting a dichroic absorption resonance at a predetermined frequency as well as birefringence at frequencies slightly above and slightly below the frequency of the absorption resonance. By applying an appropriate control voltage between the Stark cell electrodes, an electric field is generated within the Stark cell to tune the absorption resonance to overlap the frequency of an input laser beam and thereby vary the transmission through the device from maximum near resonance to zero at frequencies far away from resonance.

摘要： A system and method for focusing electromagnetic energy on a moving target. Generally, the inventive system sends a pilot beam to a target and analyzes a return wavefront to ascertain data with respect to any distortions and other phase and/or amplitude information in the wavefront. This information is then used to pre-distort an output beam by so that it is focused on the target by the intervening distortions. In an illustrative embodiment, the pilot beam is provided by a beacon laser mounted off-axis with respect to the output beam. The reflected wavefront is received through a gimbaled telescope. Energy received by the telescope is detected and processed to ascertain wavefront aberrations therein. This data is used to predistort a deformable mirror to create an output beam which is the phase conjugate of the received wavefront. In a first alternative embodiment, a nonlinear optical phase-conjugate mirror is employed to generate the required wavefront-reversed replica of the received wavefront. The system further includes an arrangement for modulating the output beam to confuse the target. In a second alternative embodiment, the system is adapted to examine atmospheric distortions of starlight to predistort the output beam. The alternative embodiment offers a faster response time and a lower susceptibility to detection.
