English to French Law/Patents Engineering (general) ring laser gyro

The present invention relates to a ring laser gyro not employing 5 piezoelectric elements for dither detection.

a dither mechanism (31) adapted to apply vibrations in laser beam propagating directions to the gyro block (11); 10 a dither controller (80) adapted to drive the dither mechanism (31);

Out of the three pairs of (i.e., six) piezoelectric elements 35 5 attached to the three deforming portions 33, two pairs are used to drive the dither mechanism 31 and the remaining one pair is used to detect dithers.
