Claim:
1. A method of automatically selecting an appropriate range of input vibration signal detection in an active vibration damper system, comprising: providing a vibration damper system for an optical structure including a vibration sensor, an actuator and a controller coupled to both the vibration sensor and the actuator by a control channel and the controller having at least two vibration feedback signal inputs with gain factors appropriate to a signal strength range for the vibration feedback signal inputs; monitoring an amplitude value of a vibration feedback signal from the vibration sensor; comparing the amplitude value of the vibration feedback signal to a pre-selected range of signal values over a pre-selected period of time; and switching the vibration feedback signal to an appropriate vibration feedback signal input with an appropriate gain factor for the amplitude value of the vibration feedback signal in the controller.
