In this paper  an image super resolution method of improving the image resolution for 1.5 times both in two directions by 4 linear arrays staggered based on this technology is presented  which avoids the large computation in a single time by use of circulation method. This method is proved effective by the digital simulation  and a simulated experiment platform is constructed to test its feasibility. The image resolution is improved for 1.42 times of the unreconstructed image according to the imaging experiment of resolution chart  which is closed to 1.5 times in ideal case. And also  the reconstructed and unreconstructed images are evaluated by the image information entropy  which proves that the reconstructed image contains more information. 2011 IEEE.   Fluorescence photobleaching properties for microarray chips 期刊论文 2010, 2010 Huang Guo-liang; Zhu Jiang; Yang Yang; Xiao Ming; Dong Zhong-hua; Deng Cheng 收藏  |  浏览/下载：5/0 Design on driving generator based on FPGA technology for TDICCD camera 期刊论文 2010, 2010 Huang Mei-ling; Zhang Bo-heng; Bian Chuan-ping; Li Lu-yao 收藏  |  浏览/下载：2/0 Environment modeling of AS-R robot based on BP Neural Network (EI CONFERENCE) 会议论文 2010 International Conference on Computer, Mechatronics, Control and Electronic Engineering, CMCE 2010, August 24, 2010 - August 26, 2010, Changchun, China Xie M.-J.; Yu X.-L.; Wang Z.-Q. 收藏  |  浏览/下载：21/0  |  提交时间：2013/03/25 There are some limitations when environment model of AS-R mobile robot is obtained by only using a separate CCD camera or ultrasonic sensor array. The BP neural network is designed to fuse information of the two sensors to obtain the robot's environment model in this paper. The input of BP neural network is the intercept and slope of the edge line obtained CCD camera and ultrasonic sensor arrays  which is processed by through the global coordinates of coordinate transformation. The output of BP network is the fused intercept and slope of the straight edge. Experiment shows that environment model is feasible for the AS-R mobile robot and the environment modeling method has more reliability and accuracy. 2010 IEEE.   Super-resolved imaging system with oversampling technology (EI CONFERENCE) 会议论文 3rd International Symposium on Advanced Optical Manufacturing and Testing Technologies, AOMATT 2007: Advanced Optical Manufacturing Technologies, July 8, 2007 - July 12, 2007, Chengdu, China Zhang X.; Liu Y.; Zhang J.-P.; Wang L.-J. 收藏  |  浏览/下载：23/0  |  提交时间：2013/03/25 It has been a significant issue in the imaging filed to provide the highest possible resolution of an electro-optical imaging system(E-O imaging system). CCD arrays are inherently undersampled and spatial frequency above Nyquist frequency is distorted so as to create ambiguity and Moire patterns for targets imaged by E-O system.. As to this drawback  a system-design project is introduced and discussed in the paper. It's well known that many image quality metrics are linked to MTF. However  CCDs don't satisfy MTF condition  namely  the shift-invariant property  so MTF synthesis can't appraise the whole system simply by the MTF product of the few sub-system ones in E-O imaging system. Then it is depicted how to solve this problem in the following. Finally the analyses and comparisons of the imaging performance parameters with and without super-resolved technologies are shown.
