摘要： In a method and apparatus for converting optical wavelength division multiplexed channels to wireless channels, the information carrying optical carriers are first demultiplexed and each optical carrier is then extracted from the data using an optical channelizing technique. The optical frequency of each of the extracted optical carriers is then shifted by an amount equal to the desired wireless carrier frequencies in the broadband wireless channels. Optical heterodyning of the frequency-shifted extracted lightwave carriers with the original data-containing optical signals, which are mutually in phase coherence, in a photodetector results in a set of wireless carriers each modulated with the data carried by the corresponding optical channel.

摘要： A method and apparatus for compensating for phase fluctuations incurred by an optical beam travelling through free space, especially a turbulent atmosphere. A transmitting station transmits a plurality of uniquely tagged optical beams through free space. The plurality of uniquely tagged optical beams are received at a receiving station, where a parameter of each uniquely tagged optical beam is quantified. Information associated with the quantified parameter for each uniquely tagged optical beam is then sent back to the transmitting station via a wireless feedback link. Using the information, the transmitting station adjusts at least one uniquely tagged optical beam to compensate for phase fluctuations.

摘要： A system for wavefront aberration reduction of an incident optical beam. The system includes a spatial light modulator (SLM) for receiving the incident optical beam and forming an output optical beam. The output beam is aberration-reduced compared to the incident beam. An interferometer receives a portion of the output optical beam and generates an interference fringe pattern by introducing a phase shift to one part of the portion of the output optical beam, the interference fringe pattern being applied to the SLM. The interference fringe pattern is representative of the wavefront error of the incident optical beam and the interference fringe pattern activates the SLM such that the SLM performs wavefront error correction on the output optical beam.

摘要： A compact sensor for detection of chemical and/or biological compounds in low concentration. The sensor comprises electromagnetic microcavities. The agent to be detected passes the microcavities, is absorbed and/or absorbed by the microcavities, and modifies the electromagnetic field inside the microcavities. After the agent has been adsorbed and/or absorbed, a probe beam is applied to the microcavities. The change of electromagnetic field is detected by the detector, and the frequency of the probe beam at which the resonance is observed, is indicative of a particular agent being present. A method for detecting chemical and/or biological compounds using the sensor.

摘要： A laser-ultrasonic inspection system is provided for on-line and off-line inspection of a workpiece. The system utilizes an optical acoustic wave generation and detection system with relatively high spatial resolution and which appreciably reduces the effects of parasitic acoustic coupling. An array of acoustic waves are generated in the workpiece by a short pulse optical transmitter bee with a beam geometry that is tailored to focus the acoustic waves at an inspection site in the workpiece. The acoustic waves that probe the inspection site are then detected by reflecting an optical read-out beam from a surface of the workpiece and optically interfering it with an optical reference beam. The geometry of the optical read-out beam is chosen such that the read-out beam only detects the acoustic waves that arrive from the inspection site (acoustic waves that arrive from other parasitic acoustic sources are out of phase with respect to each other and cancel out). A wavefront compensation system improves acoustic clutter rejection and also improves the signal-to-noise by compensating for phase and amplitude aberrations induced on the optical read-out beam by the optically rough surface of the workpiece.

摘要： A coherent input beam from a laser is fed into a Brillouin-enhanced four wave mixer which generates a phase conjugated seed beam in counterpropagation with the input beam. A brillouin amplifier is provided between the laser and four wave mixer to transfer energy from the input beam to the seed beam and thereby amplify the seed beam to produce a phase conjugated output beam with approximately 50% of the energy of the input beam and narrow bandwidth which is free from random phase jumps associated with the acoustic noise generally required to initiate and sustain stimulated Brillouin scattering. The phase conjugated output beam can be modulated or steered in direction, as desired. Reference beams for the four wave mixer may be derived from the same laser source as the input beam and have energies one or more orders of magnitude smaller than the energy of the input beam.

摘要： Associative holography memory apparatus is disclosed which employs a hologram and two phase conjugate mirrors. The mirrors are arranged to form a conjugate resonator whereby the output image from the apparatus tends to converge to that stored image most closely associated with an input image. Alternate embodiments are described which employ a multiple storage and erasure hologram, and which employ only a single phase conjugate mirror.
