Elastic surface wave gyroscope |
摘要 |
An elastic surface wave gyroscope includes two transducers attached on a piezoelectric substrate to generate elastic surface waves having different frequencies on the piezoelectric substrate, and two pair of reflectors for reflecting the different elastic surface waves toward the generators to produce two different standing waves, and another pair of reflectors for reflecting an elastic surface wave caused by a Coriolis force to produce a third standing wave, and a detector for detecting an electric signal corresponding to the third standing wave. This gyroscope has a high detection sensitivity.
