Fig. 1. System schematic. (a) System setup strategy for cpFED, where the SLM is conjugated to the entrance pupil of the objective lens and the sample surface is conjugated to the pinhole plane; (b) phase grayscale images of SLM

Fig. 2. Imaging of particle with diameter of 200 nm. (a) Solid spot (confocal) image; (b) hollow spot image, where the parts within the dotted box correspond to the same field of view; (c) cpFED image, and its size is the same as the part within the dotted boxes in (a) and (b); (d)--(f) enlarged images in the solid boxes of (a)--(c). The scale bars represent 1 μm

Fig. 3. Imaging of particle with diameter of 100 nm. (a) Confocal image; (b) cpFED image; (c) normalized intensity distributions along the section lines in (a1) and (b1); (a1) (a2) enlarged images of the white frames 1 and 2 depicted in (a); (b1) (b2) enlarged images of the white frames 1 and 2 depicted in (b). Adjacent particles that cannot be resolved in the confocal image can be resolved in the cpFED image, and the full width at half maximum reaches 133 nm. The scale bars represent 1 μm

Fig. 4. Vimentin imaging. (a) Confocal image; (b) cpFED image; (a1) (a2) enlarged images of the white frames 1 and 2 depicted in (a); (b1) (b2) enlarged images of the white frames 1 and 2 depicted in (b). The scale bars represent 1 μm
