方形孔径的宏观傅里叶叠层超分辨成像研究
摘要
Objective Fourier ptychography (FP) is a recently developed phase retrieval approach, which simultaneously realizes image restoration with super -resolution and a large field of view.This approach is also a novel super -resolution optical imaging technique that can be efficiently applied to microscopy and macroscopy respectively.However, one limitation of FP is the long acquisition and reconstruction time due to the numerous low -resolution (LR) images that are needed.Especially when the LR image is acquired under large angle illumination (dark field imaging), the low illumination intensity leads to the long exposure time of the imaging sensors.The situation becomes more time -consuming when a new sample is imaged, and thus a larger number of images with different exposure time for each LR image should be tested to obtain the
