N2 - A mechanical device has been developed as an ophthalmic ultrasonic scanning probe. The device is composed of an oscillating probe where the ultrasound transducer is mounted, part of which is flexible so the probe can oscillate when energized. Electric current is supplied to two electromagnetic coils acting on two permanent magnets mounted on both sides of the probe. A controller is employed to control the angular position of the probe during operation. Computer simulation, including the mechanical device and the controller, shows promising performance over the entire operation frequency.
