Fixation device for the actuation mechanism of a laser gyroscope.

摘要

The device is applicable to a laser rate gyro consisting of an optical block (1) mounted so as to oscillate on a support (13) and an elastic system in the form of a wheel comprising an outer ring (9) and a hub connected by thin plates (11) which are excited by piezoelectric ceramics. The optical block (1) is gripped between two gripping rings (15 and 16) attached firmly to the outer ring (9). The optical block (1) is gripped by the said rings (15 and 16) through a material (26) which is more ductile than the material of the said rings. The device is particularly useful for solving problems arising from the deformation of the optical block through stresses caused by temperature variations and from the need to dismantle the device easily. <IMAGE>
