Abstract

L'invention a trait à un gyrolaser annulaire destiné à mesurer une rotation autour d'un axe d'entrée, comportant un corps contenant une cavité polygonale formant un trajet en boucle fermée parcouru par deux faisceaux tournant en sens opposé, un miroir étant disposé à chaque angle de la cavité pour réfléchir les faisceaux, le corps du gyro présentant une forme polygonale dans laquelle deux cotés opposés sont nettement plus longs que les autres cotés qui sont petits afin de former un long corps étroit.The invention relates to an annular laser gyro intended to measure a rotation around an entry axis, comprising a body containing a polygonal cavity forming a closed loop path traversed by two beams rotating in opposite directions, a mirror being arranged at each angle of the cavity to reflect the beams, the body of the gyro having a polygonal shape in which two opposite sides are significantly longer than the other sides which are small in order to form a long narrow body.
