Optical setup of the annular illuminating LED array and condenser-based AIFPM platform. (A) The experimental setup involves an LED array board, a cemented doublet condenser, an Olympus IX73 microscope with an Olympus UPlanSApo 10× (0.40 NA) objective lens, and a scientific CMOS camera. (B) Fourier coverage using AIFPM (12 images), with an acquisition time of 0.12 s per frame. (C) OTFs under different illumination angles for FPM.
