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.

There mainly is laser digital photofinishing technique and digital photofinishing technique based on LCD consisting of TFT and LCOS in the digital photofinishing field at the present time. The former have a good many merit such as wide color gamut
high processing rate
large output size and high brightness
but his cost is very high
his maintain technique being comparatively complex
that result in difficult use for people. The utilization ratio of the latter is low because of lower resolution and lower aperture ratio for LCD
but the digital photofinishing based on LCD have lower cost and higher utilization ration
being suitable for people's current standard of living. Considering above mentioned problem
a micro-motion exposure method based on PZT piezoelectric ceramics used in digital image photofinishing is presented. The two-dimension micro-motion exposure system consisting of PZT piezoelectric ceramics
LCD panel
polarizing film and spring strip is designed. By means of PZT piezoelectric ceramics the LCD panel is removed about the one half of the pixel size of the LCD panel for four times from the original place
at the same time imaging system is exposed four times at the printing paper. The software is used to control the time synchronization
the exposure time and motion range of the LCD panel. The system has advantages such as shorter response time than 0.1seconds
lesser motion error than 0.01 microns
high stability and repeatability. Experimental results show that the proposed micro-motion exposure method improve the picture brightness and enlarge output size
at the meantime reducing the cost of the system. 2009 SPIE.

The valve-less piezoelectric pump is more suitable for minimization and microminiaturization than the valve piezoelectric pump
especially for the Microelectromechanical System (MEMS) because of its simple structure. However
in order to control the flow direction of the fluid through the pump
some assembles have to be attached outside the chamber. And it is no doubt that these assembles will take some space and hinder its further microminiaturization. In this paper
a novel valve-less piezoelectric pump with unsymmetrical corrugation chamber bottom (UCCB) is presented. It ingeniously takes advantage of the space of the chamber by developing its bottom into a unsymmetrical corrugation shape along the axis of the inlet and outlet. As a result
a series of diffuse pipes and nozzle pipes (or wedge-shaped pipes)
which substitute the regular diffuse/nozzle elements fitted outside the chamber
are alternatively formed between the unsymmetrical corrugation chamber bottom (UCCB) and the piezoelectric vibrator. The piezoelectric vibrator is opposite to the UCCB. And these diffuse pipes and nozzle pipes are able to force the fluid in the chamber to flow along a single direction when the pump works. And then the mathematic model is established to present the relationship between the mean energy loss and the flow rate of the pump. Basing on the mathematic model
the theory on the pump working is analysed. Finally
a real UCCB valve-less piezoelectric pump is manufactured
and the test with it is carried out to verify the theory above-mentioned. 2006 IEEE.
