| 摘要 |
<p>The invention concerns a device for measuring amplitude values of an oscillatory rotating motion of activation imposed on laser gyroscope to compensate its lack of sensitivity to slow rotating speeds, said oscillatory rotating motion being provided by mounting the laser gyroscope in its frame case, using fixing rings centred on the axis of activation in the shape of wheels with flexible spokes to provide a certain flexibility in rotating torque. It consists of several torque sensors (15 to 19) with piezoelectric wafer differently positioned on the spokes (in fact flexible blades (3 to 11)) of a fixing ring and whereof the output electrodes (Ea, Eb) are connected in parallel or in opposition to a common output so as to generate, in response to deformation of the spokes (3 to 11) due to the rotating movements along the activation axis, electric loads of same polarity which cumulate on the common output, and, in response to deformation of the spokes (3 to 11) derived from other movements, electric loads of opposite polarity which cancel one another on the common output, thereby enhancing the response to deformation due to rotation movements along the activation axis as compared to the response to deformation from any other source.</p> |
