UNIT OF LASER GYROSCOPES Russian patent published in 2009 - IPC G01C19/66 

FIELD: instrument engineering.

SUBSTANCE: invention refers to measurement equipment, namely to gyroscopic converter of angular rate at ring lasers. Unit of laser gyroscopes contains base frame, optical block with laser gyroscopes, mechanical oscillations sensitising device. In the unit there are six laser gyroscopes, two laser gyroscopes at each of three axes of the unit. At the base frame there are three mutually perpendicular walls. In optical block side planes that form one trihedral angle there are holes. The depth of the holes is more than the distance from the plane to the optical block centre. In the centre of optical block there is a ball. Resonant cavities that are included into holes of optical block planes and screwed to the corresponding base walls lean on the ball. At the edge of each resonator there is flat area and cavity that has the form of a ball.

EFFECT: increase of laser gyroscope unit safety and improvement of angular rate measurement accuracy.
