Abstract: The present invention relates to a system to implement a method of importing exporting data originating from a database by way of an XML file. The export method includes the steps of: selecting data from the database; requesting an export of the selected data; verifying that the selected data are not reserved in the database; constructing an export set comprising the selected data that are not reserved; reserving the selected data not reserved in the database; generating a data exchange file comprising the data of the export set, the data exchange file being constructed according to a data exchange file model, the file model describing types of data, links between the types of data, existing in the database; and transferring the exchange file generated to the second computer.

Abstract: A device for harmonizing a laser beam path with an observation path for a target includes a laser that generates a laser beam; a first optical element that directs a first part of the laser beam toward the target along the laser beam path while directing a second part of the laser beam toward a conversion device; and a second optical element that directs a converted beam from the conversion device to a sensor that receives the converted beam and an image from the target. The conversion device includes a photoluminescent material that converts the second part of the laser beam into a converted radiation having a wavelength within a spectral band of the sensor, and an optical assembly that focuses the second part of the laser beam into the photoluminescent material and that collects at least a portion of the converted radiation to form the converted beam. The photoluminescent material can include photoluminescent ions such as erbium ions, or a semiconductor material such as indium arsenide.

Abstract: A telemeter is used to measure the distances between a sequence of points on a target surface. The telemeter includes an emitting source provided with a pulsed laser sending out a pencil of light energy in a determined direction of sight, a contra-rotating wedge communicating, to the pencil, a deflection along an epicycloidal type of scanning pattern in a plane perpendicular to the axis of sight, and a receiver including the same contra-rotating wedge and a photodiode. The disclosed device can be applied more particularly to a system for the detection of obstacles of a wire-shaped type.

Abstract: A method and system for the avoidance of collisions among aircraft in which monochromatic radiation is transmitted from an aircraft fitted out with a wide-field optical transceiver. The monochromatic radiation scans the space around the aircraft which defines a zone of proximity. Optical radiation is returned after back reflection off objects which may be sources of danger constituted by other aircraft that have entered the zone of proximity. The radiation received is detected and then processed to deduce therefrom the direction and, as the case may be, the distance of the source of danger. Such a method can be applied especially to the avoidance of collision between non-cooperating aircraft.

Abstract: A collision-avoidance method for cooperating carriers consists of:transmitting, from each carrier, monochromatic pulsed light waves, coming from at least two wide-field optical transmission devices to cover the space around the carrier and thus define a zone of proximity, the power of the optical transmission defining, under given weather conditions, the range of the transmission and hence the zone covered;and receiving, at each carrier, the monochromatic, pulsed light waves radiated into space by other cooperating carriers, on at least two wide-field reception devices covering the space around the carrier. Each intrusion of a carrier into the proximity zone of another carrier prompts the detection of light radiation and the triggering of an alarm on either carrier. Applications are to air anti-collision systems.

Abstract: In a system of optical communications that can be used by air or space vehicles, each station comprises at least one optical system covering a half space, this system comprising two twinned optical devices to respectively form two distinct reception channels: a first reception optical channel for the initialization, in space, of the direction of communication; a second optical channel for the reception of the contents of the communication. One of the two optical devices is also used to form a transmission channel for the initialization and then for the communication in the direction of communication. The setting up of communication is done in three steps, respectively target designation, iterative bilateral acquisition and interstation communication.
