High quality imaging can be realized at any region of interest (ROI) within the field-of-view (FOV) by utilizing the SLM to correct the aberration of different regions dynamically. A reflective cassegrain optical structure is proposed  which is designed  optimized and matched with the reflective SLM to construct a more practical foveated imaging system. This reflective imaging system has a large aperture so that enough light can reach the image plane. It also makes the total length of the system shorter and therefore more practical. We also simulate and analyze the system. This kind of foveated optical imaging system can be applied in wide FOV imaging aspects to reduce bandwidth and optics complexity  and to achieve weight reduction and miniaturization. 2010 Copyright SPIE - The International Society for Optical Engineering.   近似骨架导向的归约聚类算法 期刊论文  OAI收割 电子与信息学报, 2009, 卷号: 31, 期号: 12, 页码: 2953-2957 宗瑜; 李明楚; 江贺 收藏  |  浏览/下载：24/0  |  提交时间：2011/03/18 聚类问题  NP-难解  启发式算法  近似骨架  Clustering issue  NP-hard  Heuristic algorithm  Approximate backbone  骨架导向  归约  聚类算法  optimal solutions  近似骨架  search space  局部最优解  clustering algorithm  Reduction Algorithm  聚类问题  high quality  算法收敛速度  数据集  研究成果  搜索空间  实验结果  聚类质量  基本思想  骨架特征  multipleCluster analysis  Computational complexity  Feature extraction  Heuristic algorithms  Heuristic methods  Optimal systems   ltl model checking via search space partition 会议论文  OAI收割 6th International Conference on Quality Software, Beijing, PEOPLES R CHINA, OCT 27-28, Pu Fei; Zhang Wenhui   |  收藏  |  浏览/下载：27/0  |  提交时间：2011/07/28 LTL model checking  complexity reduction  compositional verification  memory requirement  nondeterministic choice  search space partition  state space explosion  computational complexity  formal verification  search problems   ltl model checking via search space partition 会议论文  OAI收割 6th International Conference on Quality Software, Beijing, PEOPLES R CHINA, OCT 27-28, Pu Fei; Zhang Wenhui   |  收藏  |  浏览/下载：22/0  |  提交时间：2011/07/28 LTL model checking  complexity reduction  compositional verification  memory requirement  nondeterministic choice  search space partition  state space explosion  computational complexity  formal verification  search problems   The primal-dual potential reduction algorithm for positive semi-definite programming 期刊论文  OAI收割 JOURNAL OF COMPUTATIONAL MATHEMATICS, 2003, 卷号: 21, 期号: 3, 页码: 339-346 作者:  Huang, SM   |  收藏  |  浏览/下载：11/0  |  提交时间：2018/07/30 positive semi-definite programming  potential reduction algorithms  complexity
