Abstract (en)

The system has a converter for an excitation beam (FE) with propagation and divergence directions linked to those of the laser beam (FL) in a retropropagation beam (FC). The excitation beam is formed by a fraction of the laser beam, and the converter (22) is made from a photoluminescent material which, when excited to the wavelength of the excitation beam, emits radiation at a wavelength within the spectral range of the detector (DET). It also has an optical assembly for focusing the excitation beam on the photoluminescent material and collecting at least part of the emitted radiation for the retropropagation beam.

Abstract (fr)

L'invention concerne un dispositif pour l'harmonisation entre une voie d'émission comportant un laser (LAS) émettant un faisceau laser (FL) et une voie passive d'observation comportant un capteur (DET). Le dispositif selon l'invention comporte des moyens de conversion d'un faisceau d'excitation (FE) dont la direction de propagation et la divergence sont liées à celles du faisceau laser (FL) en un faisceau rétropropagatif (FC). Selon un exemple, le faisceau d'excitation est constituée d'une fraction du faisceau laser (FL). Les moyens de conversion comprennent un matériau photoluminescent (22) qui, excité à la longueur d'onde du faisceau d'excitation (FE), émet une radiation dont la longueur d'onde est comprise dans la bande spectrale du capteur (DET). Ils comprennent en outre un ensemble optique (21) permettant de focaliser le faisceau d'excitation (FE) dans le matériau photoluminescent et de collecter au moins une partie de la radiation émise pour former le faisceau rétropropagatif (FC). Le dispositif comporte également des moyens optiques pour envoyer le faisceau rétropropagatif (FC) sur le capteur permettant ainsi de repérer les défauts d'harmonisation. <IMAGE>
