ABSTRACT:
A force is produced within an object by an ultrasonic beam. The frequency of this force is equal to the frequency of a signal used to modulated the amplitude of the beam. The sonic waves produced by the object in response to the force can be used to detect the presence of objects or to image objects based on their mechanical properties. It can also be used to regenerate a desired audio signal in the object.
