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.
