Abstract Procedure for attenuating linearity errors in a ring type laser rate- gyro that uses N mirrors arranged in such a way that the laser beams travel along two identical polygons in opposite directions, characteri- sed by the fact that at least one of the mirrors that define the tra- jectory of the two laser beams is made to oscillate angularly with res- pect to the body of the rate-gyro about an axis perpendicular to the plane defined by these two laser beams ; the rotational axis of each of the oscillating mirrors being for preference as close as possible to the perpendicular to the mirror being considered that passes through the point of contact of the laser beams with the mirror in question.
