关键词	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.
