Abstract: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 Ultrason… Show more
