摘要： For transmitting information via laser beams to and from other similar laser communication transceivers. Each transceiver comprises a wavelength locked beacon laser providing a beacon beam. The transceivers determine the precise location of other transceivers by detecting these beacon beams with beacon receive units comprising atomic line filters matched to the beacon wavelength. Signals are transmitted by imposing an electronic signal on laser beams produced by one or more signal laser devices. These signals are directed with precision at other transceivers, and the signal beams are detected with very narrow field of view signal receive units. In a preferred embodiment, these transceivers are installed on 66 satellites in low earth orbit and on selected mountain tops on earth to provide a global communication system.

摘要： A particle detection system uses a reflective optic comprising a curved surface to detect high angle scattered light generated by a particle in a liquid medium, when a laser beam is incident on the particle. When the particles transit the laser beam, light is scattered in all directions and is described by MIE scattering theory for particles about the size of the wavelength of light and larger or Rayleigh Scattering when the particles are smaller than the wavelength of light. By using the reflective optic, the scattered light can be detected over angles that are greater than normally obtainable.

摘要： A particle detection system uses illumination incident at an angle to detect particles in a liquid such as water. By using illumination incident at an angle, the scattered light can be measured through a range of angles that are greater than the measured range of angles produced when the illumination is incident at a normal angle, when using the same detector. For example, the light can be measured through an angle that is twice that produced with illumination incident at a normal angle.

摘要： A system and method for controlling the power of a transmitter helps to ensure that the transmitted signal is within the dynamic range of the intended receiver. The transmitted signal is received by the receiver. The received signal strength is measured to determine its power level in relation to the dynamic range of the receiver. Where the signal strength is too high, the transmitter is slewed to effectively decrease its pointing accuracy, thereby causing a lower-power portion of the transmitted signal to impinge upon the receiver. Similarly, where the signal strength falls below a desired level, the transmitter is slewed back toward the center-pointing position, effectively increasing its pointing accuracy, and thereby increasing the signal strength received at the receiver.

摘要： Disclosed are radiation-resistant zone plates for use in laser-produced plasma (LPP) devices, and methods of manufacturing such zone plates. In one aspect, a method of manufacturing a zone plate provides for forming a masking layer over a supporting membrane, and creating openings through the masking layer in a diffractive grating pattern. Such a method also provides depositing radiation absorbent material in the openings in the masking layer and on the supporting membrane, and then stripping the remaining portions of the masking layer. Then, portions of the supporting membrane not covered by the absorbent material are removed, wherein the remaining portions of the supporting membrane covered by the absorbent material form separate grates. Also in such methods, cross-members are coupled to the grates for holding positions of the grates with respect to each other.

摘要： A lens assembly for enhancing the depth of field of a short-wavelength microscopic system is disclosed. The lens assembly includes an objective zone plate lens, an encoding lens, an imaging detector and a decoding component connected to the imaging detector. The objective zone plate lens is oriented to receive short-wavelength radiation that has passed through a sample in a microscopic system. The encoding lens is oriented to receive the short-wavelength radiation that has passed through the objective zone plate lens and encode the radiation to output an encoded short-wavelength radiation. The imaging detector is oriented to receive the encoded short-wavelength radiation and convert it to a digital signal which is subsequently decoded by the decoding component to decode the encoding applied to the short-wavelength radiation.

摘要： A laser radar system capable of measuring windspeed to within 1 m/s at distances in the range of 10 km. The system comprises two Faraday atomic line filter/detectors combinations, a first filter-detector which consist of a metal vapor cell located between crossed polarizers. A magnetic field is applied to the cell which Zeeman splits the energy levels resulting in different absorption lines for left and right circularly polarized light. Near these lines the filter acts as a Faraday rotator providing rotary power only in the vicinity of an absorption line, which provides the 90 degree rotation necessary to pass the second polarizer. At higher fields and vapor densities multiple rotations lead to rapid modulations in the transmission spectrum. Away from the absorption line the filter provides an out of band rejection that is determined by the extinction ratio of the crossed polarizers. By tuning the temperature and the magnetic field in each Faraday filter sharply crossing response curves can be produced. A preferred lasing frequency range is a frequency range covering a portion of one of the slopes of the peak of the first filter and a portion of one of the opposite direction slopes of one of the peaks of the second filter. Within this range an increase in the frequency of signal light will result in a greater fraction of the light detected by one filter-detector and a smaller fraction detected by the other filter-detector and a decrease in the frequency of the signal light will have the opposite effect. In a preferred embodiment of this invention laser pulses from a laser operating near the midpoint of this preferred frequency range are beamed at a target which could be a windy portion of the atmosphere. Backscattered Doppler shifted light from aerosols and particles in the atmosphere are collected by a telescope and split into two parts, one part being directed to each filter-detector. The intensities of the light detected by the filter-detectors are compared and the relative magnitudes are used to determine the windspeed in the direction of the laser beam. Pulses can be made very short and the travel time of the light is used to determine the range so that a map of windspeed as a function of range is provided in the direction of the laser beam.
