ABSTRACT:
The resonator (10) includes a monocrystal (11) of a nonpiezoelectric matel with low attenuation of elastic bulk waves, such as corundum, means of supporting the monocrystal fastened to the monocrystal at points corresponding to the vibration nodes, thermal means (40) for directly causing a proper excitation of the monocrystal (11) and optical means (50) for detecting the periodic motion of the resonator without contact. Application in particular in oscillator construction.
