摘要: A system for controlling aeraulic conditions existing above an aerial arrival zone includes anemometric components and aeraulic components. The anemometric components deliver speed and bearing angle values that characterize a relative wind speed with respect to the aerial arrival zone and to a superstructure located close to the aerial arrival zone. The aeraulic components are capable of modifying air movements above the aerial arrival zone, and are controlled according to the wind speed and bearing angle values. Such a system is particularly suitable for use on board a ship able to carry a helicopter, in particular on its afterdeck.

摘要: An array antenna is formed from delay lines, and includes radiating elements which are individually connected to line patterns of the delay lines. Such an array antenna structure can be implemented by printed circuit technology and can be used to establish radio links for data communication between a mobile carrier, such as an aircraft, and a geostationary satellite.

摘要: An imaging optical system including three mirrors has a configuration adapted to block stray rays which could otherwise reach an image sensor of the system, while permitting large fields, high apertures, and good system compactness. The system may also incorporate two entrance baffles which are arranged one on either side of an optical entrance of the system. Functions of the two entrance baffles may be limited to intercepting rays originating from fields which are angularly distant from the entrance field useful to each captured image. The two entrance baffles can thus have reduced lengths upstream, so that the system has a small size.

摘要: An inertial angular position sensor includes at least three identical resonators which are arranged symmetrically about a sensitive axis of the sensor, so that a rate gyro constructed from the sensor has an integrating operation. The sensor further includes a coupling element which connects a vibrating portion of each resonator to the vibrating portions of all other resonators of the sensor. Preferred configurations for the inertial angular position sensor allow obtaining integrating rate gyros with high sensitivity and low production cost.

摘要: Disclosed is an instrument including a multipath, monolithic optical component, made up of a portion of a transparent material between two opposite faces of the component. One of the two faces of the component is formed by a first refracting surface, and the other face includes several second refracting surfaces which are juxtaposed. Each optical path of the component is formed by one of the second refracting surfaces in combination with a corresponding portion of the first refracting surface. One such component is suited for being part, within the instrument, of a detection module with multiple optical paths arranged in parallel, with a matrix photodetector shared by the optical paths. Such a detection module may be compact enough in order to be integrated into a cryostat cold screen, improving cooling thereof, and may be combined with an objective in order to form an instrument with multiple optical paths.

摘要: A process and system for detection and telemetry using electromagnetic radiation pulses allows characterization of a radial velocity distribution as a function of a separation distance within an exploration zone. An impulse response from the system is used for decomposing a measurement signal which is collected for each acquisition sequence performed for a useful measurement. The result of the decomposition includes an estimate of the radial velocity distribution as a function of the separation distance.

摘要: An antenna (100) for emitting radiation from at least one electromagnetic traveling wave which propagates along a guide path is designed to reduce reflection of the traveling wave likely to occur at the end of the guide path. To this purpose, the guide path has at least one portion in the form of a spiral segment (11, 12), which is connected to another portion of the guide path in the form of a loop (13). Gain in the antenna's reflection coefficient can be obtained in this manner, which is effective in particular near a lower frequency limit of a transmission band of the antenna.

摘要: A method of photothermal analysis of a solid piece includes injecting heat into a region of a surface of the piece, called heating region, capturing a thermal analysis image of a detection region which is distinct from the heating region, then subtracting a reference image from the thermal analysis image. The reference image corresponds to a thermal emission distribution as caused by the injected heat for a case where the surface portion of the piece is without defects. Such method makes it possible to reduce an analysis cycle time for the piece, and to reduce a signal-to-noise ratio of images capable of revealing defects present in the surface portion of the piece.

摘要: A LIDAR system is adapted for performing anemometrical measurements relating to a focusing zone of a laser beam which is emitted by the system. The system includes a temporal control device for the laser beam, which is adapted for putting this laser beam in successive laser pulse form, so that each laser pulse has an individual length which is greater than or equal to twice the Rayleigh length divided by the propagation speed of the laser pulses in the atmosphere, and less than 20 μs. Advantageously, the individual length of each laser pulse is between 0.2 and 5 times the coherence time of the atmosphere which is effective in the focusing zone. Such a LIDAR system provides values for a spectral CNR ratio which are better than those of systems from the state-of-the-art, at equivalent spatial resolution.
