摘要
叠层扫描成像和傅里叶叠层扫描成像可增大视场和提高分辨率。基于多距离/多高度轴向扫描和薄柱透镜旋转扫描的计算成像技术采用相位恢复算法,可以高精度重建目标的复数光场。这些成像技术在扩大视场和提高分辨率方面具有显著优势。介绍了含变参数的光学相干衍射系统在计算成像方面的研究进展。作为间接成像形式,多参数成像技术是一类将衍射成像与算法相结合的计算成像技术,实现了复值光场的精确多维表征。
Ptychographic iterative and Fourier ptychographic imaging techniques can enhance field of view(FOV)and resolution.The parameter-changed computational imaging technique based on multi-disntance/multi-height axial scanning and thin cylinder rotation can be used with phase retrieval algorithms to reconstruct the complex-valued fields of objects with high resolution.These imaging techniques possess prominent advantages for enlarging FOV and resolution.We review the recent research progress of the parameter-changed optical coherent diffraction imaging systems in the field of computational imaging.As a kind of indirect imaging tools,the multi-parameter imaging technique combines diffraction imaging with algorithms,which can be used to realize the accurate multi-dimensional characterization of a complex-valued light field.
