Abstract
A vibratory gyroscope is provided that includes a vibratory element; a vibration inducing device for inducing a mode of vibration into the vibratory element; and a processing device for generating, in response to a change in strain detected in the vibratory element, a signal indicative of a rate of rotation about an axis of the vibratory element corresponding to a rotation imparted to the vibratory element subsequent to an inducing of the vibration. The vibration inducing device includes an acoustic signal source provided at a location spaced from the vibratory element. Undesirable effects associated with mounting the vibration inducing device to the vibratory element are thereby avoided.
