摘要： An ultraviolet laser generates a coherent beam, which is downconverted to produce pairs of frequency-entangled photons. For each entangled pair, a first photon is sent along a first path and a second photon is sent along a second path. A first detector detects those photons sent along the first path, and a second detector detects those photons sent along the second path. The detection is performed in a single photon regime. Coincidence counting is performed on outputs of the detectors, including comparing leading edges on outputs of the first and second detectors within a time window.

摘要： A method and apparatus for clearing an optical channel for transmitting data through free space between a first and second location includes a light beam, wherein the light beam has a spatially and/or time-dependent modulated intensity profile, and is substantially collimated so that the intensity profile is conserved over a specified distance of operation. The light beam includes a cross-sectional profile having regions of low and high intensity, portions of which are provided for the transmission of an optical data signal. A light source wavelength and intensity are selected for types of obscurant particles having optical properties whereby the radiation pressure acts on the particles, and the particles may then be either attracted into or repelled from portions of the spatially modulated optical beam, leaving certain portions of the optical channel beam absent of obscurant particles, thereby enabling transmission of optical data through the cleared optical channel with low attenuation.

摘要： An optical detection apparatus includes a housing having a circumferential opening therein. A primary mirror reflects light rays to form a first set of light rays to a secondary mirror that has a generally concave shape coupled to the housing. A tertiary mirror having a generally concave shape coupled to the housing spaced apart from the secondary mirror directs light to detection optics that form an image using the third set of light rays. The detection optics include a micro-mirror array that redirect the image to a detector. A controller controls the micro-mirror array and determines an event characteristic based upon the image thereon.

摘要： A heterodyne interferometer and an associated interferometric method are provided that significantly reduce polarization crosstalk and that permit the target to translate to a limited extent in a direction orthogonal to the direction of interest and to be tilted to a limited extent without adversely affecting the resulting measurement. The heterodyne interferometer includes a beamsplitter for splitting each of a first beam and a coherent second beam into at least two partial beams. Advantageously, the first beam and the partial first beams propagate in a first plane, while the second beam and the partial second beams propagate in a second plane that is offset from the first plane by at least two beam diameters so as not to spatially overlap with the first beam and the partial first beams, thereby preventing polarization crosstalk. The heterodyne interferometer also includes a reference arm and a measurement arm that each receive a partial first beam and a partial second beam. The measurement arm can include a pair of crossed porro prisms with at least one of the porro prisms being adapted to move in conjunction with the target. By utilizing the pair of crossed porro prisms, the target can translate to a limited extent in a direction orthogonal to the measurement path and can be tilted to a limited extent without adversely affecting the resulting measurements. The heterodyne interferometer can also include at least one and, more commonly, a pair of detectors for receiving partial beams that have traversed the reference arm and the measurement arm. Based upon the resulting interference fringes, the detector can provide a signal indicative of the target displacement.

摘要： A system, apparatus, and method are disclosed for a super-resolution imaging radar (SRIR). The SRIR employs a pulse signal generator that propagates bursts of radio frequency (RF) energy. Each burst contains a number of pulses. One pulse of each burst is an ancilla pulse, and the remaining pulses are propagated towards an object. An array bucket detector (ABD) collects pulses that are reflected from the object. Also, the ancilla pulses are propagated through a virtual lens. A virtual scanning detector detects the virtual ancilla electric field. A processor calculates a virtual ancilla electric field, which would be present at the scanning detector. Further, a coincidence circuit calculates a cross-time correlation function of the electric fields of the reflected pulses that are collected by the ABD and the virtual ancilla electric field. The coincidence circuit uses cross-time correlation function results to generate pixels of an image of the object.
