Abstract

Based on a bright‐field microscope with a programmable LED array light source, accelerated Fourier ptychographic diffraction tomography (aFPDT) technique employing a hybrid strategy of sparse annular and multiplexing illuminations was developed to achieve large field‐of‐view and high‐resolution 3D RI tomographic imaging. Compared with previous work, aFPDT enables the reducing of intensity data requirement by more than 40 times and to achieve computational acceleration of 3D tomographic reconstruction. aFPDT has the potential to advance its widespread applications in biomedicine.Further details can be found in the article by Shun Zhou, Jiaji Li, Jiasong Sun, Ning Zhou, Qian Chen, and Chao Zuo (e202100272).image
