Torsion oscillator stabilization

A torsion oscillator (FIG. 1 ) is stabilized in operation by determining the current resonant frequency ( 62 ); in a first procedure, observing the oscillator for change in resonant frequency ( 64 ), and then restoring the amplitude and median offset ( 66 ) without changing the drive frequency. In a...

description	A torsion oscillator (FIG. 1 ) is stabilized in operation by determining the current resonant frequency ( 62 ); in a first procedure, observing the oscillator for change in resonant frequency ( 64 ), and then restoring the amplitude and median offset ( 66 ) without changing the drive frequency. In an alternative procedure, after determining the resonant frequency ( 62 ); setting the drive frequency close to but offset from the current resonant frequency ( 74 ), observing the oscillator for change in resonant frequency ( 76 ), and the restoring the close offset to the changed resonant frequency ( 78 ). By operating slightly off peak, the direction of resonant change is immediately known. The first procedure has less difficulties in implementation, but requires more power.
