Firstly  according to the work principle of the area CCD  FPGA is adopted to realize the timing driving and multichannel and parallel analog signal handling to raise the export frame frequency of the area CCD. Secondly  with an image compression scheme based on FPGA embedded processor MicroBlaze and ADV212 compression chip  real time image compression and the high speed area CCD are realized. Finally  by detecting the analog signal of the area CCD output  the real time compression of the big area CCD image is carried out in different compression ratios and the compression performance is analyzed. Experiment result shows that this scheme can realize real time image compression with the biggest data rate of 520Mbps. When compression bit ratio is 0.15  the signal-to-noise ratio of peak value can reach 36 dB. Image collection and image compression are integrated  which reduces the data transmission between them and improves systematic integration degree.   Carbon isotope ratios of C-4 plants in loess areas of North China 期刊论文  OAI收割 SCIENCE IN CHINA SERIES D-EARTH SCIENCES, 2006, 卷号: 49, 期号: 1, 页码: 97-102 作者:  Wang, G;  Han, JM;  Zhou, LP;  Xiong, XG;  Tan, M   |  收藏  |  浏览/下载：9/0  |  提交时间：2018/09/26 C-4 plants  carbon isotope ratios  loess area   Carbon isotope ratios of C-4 plants in loess areas of North China 期刊论文  OAI收割 SCIENCE IN CHINA SERIES D-EARTH SCIENCES, 2006, 卷号: 49, 期号: 1, 页码: 97-102 作者:  Wang, G;  Han, JM;  Zhou, LP;  Xiong, XG;  Tan, M   |  收藏  |  浏览/下载：17/0  |  提交时间：2018/09/26 C-4 plants  carbon isotope ratios  loess area   Pollen indication to source plants in the eastern desert of China SCI/SSCI论文  OAI收割 2005 Li Y.
