<p>A device for eliminating parasitic rotations of the mobile mirrors (15) of gyrolasers driven by piezoelectric ceramics (11). These parasitic rotations are caused by deformations of the external part (12) which constitutes the body of the mobile mirror and is attached to the optical block (1) under the effect of the accelerations of the activating motion. These parasitic rotations are corrected in the invention by semi-circular ceramics (26) glued around the external part (12), which, when driven by an electronic circuit, correct the deformations of the said external part (12). The invention is applicable to all lasers and in particular to gyrolasers.</p> |
