Abstract

Abstract Translated from French Le dispositif de compensation comporte, sur la trajectoire du faisceau laser entre l'émetteur (1) et l'unité d'utilisation (5), des moyens de compensation (2) mobiles comprenant au moins deux surfaces réfléchissantes (3,4) disposées sur le trajet du faisceau laser, les axes normaux aux plans des deux surfaces réfléchissantes étant de préférence orthogonaux et les surfaces réfléchissantes étant placées de telle sorte que le faisceau laser sortant desdits moyens de compensation soit parallèle au faisceau y entrant, les surfaces réfléchissantes étant mobiles séparément et/ou simultanément, leur déplacement étant assujetti à la condition que la trajectoire parcourue par le faisceau laser depuis l'émetteur jusqu'à l'unité d'utilisation doit être égale à une constante. The compensation device comprises, on the path of the laser beam between the emitter (1) and the use unit (5), mobile compensation means (2) comprising at least two reflecting surfaces (3,4) arranged along the path of the laser beam, the axes normal to the planes of the two reflecting surfaces being preferably orthogonal and the reflecting surfaces being placed so that the laser beam leaving said compensation means is parallel to the beam entering it, the reflecting surfaces being movable separately and / or simultaneously, their movement being subject to the condition that the path traveled by the laser beam from the transmitter to the unit of use must be equal to a constant.
