随着对成像系统研究的深入，基于光学元件几何操作的成像方式为光学成像系统带来更优越的成像特性，如结构光技术和叠层成像技术等在提升分辨率和光学信息多维获取方面带来重要贡献。本申请项目以薄柱透镜旋转扫描模型设计超分辨计算成像系统，并研究其成像机理，旨在光学多维数据获取和超分辨成像方面获得突破性进展。应用矩阵光学和衍射理论研究薄柱透镜旋转扫描光学成像系统的信息传输规律，通过级联菲涅尔衍射和卷积理论确定光学衍射成像过程计算方法，并将其应用于光场复振幅的精密重构计算。相比于轴向移动透镜成像系统，横向截面内旋转薄柱透镜系统可以避免在重构过程中采样率的变化，因此相应重构图像数据的精度更高，因无需考虑调整采样率而使得数据处理环节极大简化。降维信息获取和非线性叠层扫描是本申请项目另外两个突出优势。

With the extensive study of imaging system, imaging ways based on geometrical operations of optical elements have some advantages of imaging properties for optical imaging system. For example, structured light technique and ptychographic imaging technique make significant contributions at the aspects of super resolution enhancement and optical information multi-dimensional acquisition. This project will design super resolution imaging system by using rotation scanning with thin cylinder lens. Its imaging mechanism will be explored, in order to achieve optical information multi-dimensional acquisition and super resolution imaging. Information transmission rules through the optical imaging system including thin cylinder lens are analyzed by matrix optics and diffraction theory. The computational method of optical diffraction imaging process is determined by cascaded Fresnel diffraction and convolution operations. The method will be used in accurate reconstruction calculation of the complex amplitude of light field. To compare measurement and imaging system composed of axis translation of lens, the rotation structure on cross section can avoid the change of lateral sampling ratio during reconstruction process. Thereby the corresponding recovered image has better precision. Data processing operations are simplified tremendously since the operations adjusting sampling ratio are not utilized. The information acquisition by dimension reduction and nonlinear ptychographic scanning are two outstanding advantages of this project as well.
