| 1 | Imaging through unknown scattering media based on physics-informed learning显示文摘Imaging through scattering media is one of the hotspots in the optical field, and impressive results have been demonstrated via deep learning(DL). However, most of the DL approaches are solely data-driven methods and lack the related physics prior, which results in a limited generalization capability. In this paper, through the effective combination of the speckle-correlation theory and the DL method, we demonstrate a physics-informed learning method in scalable imaging through an unknown thin scattering media, which can achieve high reconstruction fidelity for the sparse objects by training with only one diffuser. The method can solve the inverse problem with more general applicability, which promotes that the objects with different complexity and sparsity can be reconstructed accurately through unknown scattering media, even if the diffusers have different statistical properties. This approach can also extend the field of view(FOV) of traditional speckle-correlation methods. This method gives impetus to the development of scattering imaging in practical scenes and provides an enlightening reference for using DL methods to solve optical problems. | SHUO ZHU ENLAI GUO JIE GU LIANFA BAI JING HAN | 2021 | Photonics Research2021,9,5: | 10 |
| 2 | Optimal decision-making model of spatial sampling for survey of China's land with remotely sensed data显示文摘In the remote sensing survey of the country land, cost and accuracy are a pair of conflicts, for which spatial sampling is a preferable solution with the aim of an optimal balance between economic input and accuracy of results, or in other words, acquirement of higher ac-curacy at less cost. Counter to drawbacks of previous application models, e.g. lack of compre-hensive and quantitative-comparison, the optimal decision-making model of spatial sampling is proposed. This model first acquires the possible accuracy-cost diagrams of multiple schemes through initial spatial exploration, then regresses them and standardizes them into a unified ref-erence frame, and finally produces the relatively optimal sampling scheme by using the discrete decision-making function (built by this paper) and comparing them in combination with the dia-grams. According to the test result in the survey of the arable land using remotely sensed data, the Sandwich model, while applied in the survey of the thin-feature and cultivated land areas with aerial photos, can better realize the goal of the best balance between investment and accuracy. With this case and other cases, it is shown that the optimal decision-making model of spatial sampling is a good choice in the survey of the farm areas using remote sensing, with its distin-guished benefit of higher precision at less cost or vice versa. In order to extensively apply the model in the surveys of natural resources, including arable farm areas, this paper proposes the prototype of development using the component technology, that could considerably improve the analysis efficiency by insetting program components within the software environment of GIS and RS. | LI Lianfa1,2, WANG Jinfeng1 & LIU Jiyuan1 1.

| 3 | 对钢管材料在液压膨胀试验中的应力-应变关系的测定显示文摘基于塑性膜理论和力平衡方程等,对试验数据进行曲线拟合,来确定在液压成形过程(THF)中薄壁管的应力-应变关系。由此提出一种简单实用的液压膨胀试验方法,并对不锈钢和低碳钢管进行自由膨胀试验,以得到所需的试验变形数据。而自由膨胀的有限元模拟同时也验证了该方法的有效性。结果表明:目前的做法是正确的,可用于对钢管材料的应力-应变性能进行界定,此外,由此法也可得到扩展的大应变流动应力曲线。 | Yang Lianfa and Guo Cheng | 2008 | 钢结构2008,23,7: | 7 |

| 5 | Integrated spatial sampling modeling of geospatial data显示文摘Spatial sampling is a necessary and important method for extracting geospatial data and its methodology directly affects the geo-analysis results. Counter to the deficiency of sepa-rate models of spatial sampling, this article analyzes three crucial elements of spatial sampling (frame, correlation and decision diagram) and induces its general integrated model. The program of Spatial Sampling Integration (SSI) has been developed with Component Object Model (COM) to realize the general integrated model. In two practical applications, i.e. design of the monitoring network of natural disasters and sampling survey of the areas of non-cultivated land, SSI has produced accurate results at less cost, better realizing the cost-effective goal of sampling toward the geo-objects with spatial correlation. The two cases exemplify expanded application and convenient implementation of the general integrated model with inset components in an inte-grated environment, which can also be extended to other modeling of spatial analysis. | LI Lianfa WANG Jinfeng | 2004 | Science China Earth Sciences2004,47,3: | 2 |
