Drift angle is a transverse intersection angle of vector of image motion of the space camera. Adjusting the angle could reduce the influence on image quality. Ultrasonic motor (USM) is a new type of actuator using ultrasonic wave stimulated by piezoelectric ceramics. They have many advantages in comparison with conventional electromagnetic motors. In this paper
some improvement was designed for control system of drift adjusting mechanism. Based on ultrasonic motor T-60 was designed the drift adjusting system
which is composed of the drift adjusting mechanical frame
the ultrasonic motor
the driver of Ultrasonic Motor
the photoelectric encoder and the drift adjusting controller. The TMS320F28335 DSP was adopted as the calculation and control processor
photoelectric encoder was used as sensor of position closed loop system and the voltage driving circuit designed as generator of ultrasonic wave. It was built the mathematic model of drive circuit of the ultrasonic motor T-60 using matlab modules. In order to verify the validity of the drift adjusting system
was introduced the source of the disturbance
and made simulation analysis. It designed the control systems of motor drive for drift adjusting system with the improved PID control. The drift angle adjusting system has such advantages as the small space
simple configuration
high position control precision
fine repeatability
self locking property and low powers. It showed that the system could accomplish the mission of drift angle adjusting excellent. 2011 SPIE.

This paper presents a new wavelength-selective switch by combining silicon micromaching and microassembly techniques. The 18 wavelength-selective switch (WSS) based on micro electro mechanical systems (MEMS) technology is proposed and fabricated with micro electromagnetic actuators
8 WXC prototype node is implemented by using 18 WSSs as building elements. The working principle and the configuration of the micro electromagnetic actuator are illuminated. By analysis
reflecting prisms and narrow-band thin films filters. And a 8
the property suits for the application when the inputs are 2V
and the best fiber-to-fiber insertion loss 5dB is gotten.
