Abstract
A scanning apparatus and method for scanning an object including a frame, a transducer for obtaining information from an object and a motor oscillating the transducer. The motor comprises a spring/solenoid combination driven at the resonant frequency of the spring/motor system. The actual displacement of the transducer is measured and compared to a desired displacement to provide a control signal to the motor. The scanning apparatus is at least partially enclosed by a housing containing a heat transfer fluid for damping the resonant vibration of the apparatus.
