In order to meet special requests of optical imaging sensor in scene matching navigation system  a disc varifocal mechanism is proposed for the flight vehicles of long flying time and range. Within small space occupied  it can obtain real images with various resolutions. Moreover  using plate traveling-wave Ultrasonic Motor as its driven motor can reduce energy loss  improve control precision and ensure image obtaining being real-time and stable. Disc varifocal mechanism driven by plate traveling-wave Ultrasonic Motor is high-response  and variation in load doesn't affect its performance parameter. Therefore  applying disc varifocal mechanism in scene matching navigation system  combing software and hardware  can obviously improve the accuracy  real-time and robust of scene matching navigation system. The experiment showed that when the weight of mechanism was 1.5kg  the shortest starting was 0.6ms  and the shortest shutoff was 0.5ms. 2009 IEEE.
