High-resolution volumetric imaging using hybrid image of Fourier light-field microscopy and wide-field microscopy

Abstract

We have developed wFLFM to further enhance the resolution by taking the advantage of both wide-field image and FLFM. We proposed the principle of wFLFM and verified the approach both numerically using simulated rings, and experimentally using phantom samples on the wFLFM system we constructed as a prototype. The principle of wFLFM requires only additional wild-field image at the aperture plane, making it readily compatible with various extended depth of focus wide-field modules, and the validating results showed a 2-3× enhancement in lateral resolution without cost in axial information, thereby advancing wFLFM as a promising high-resolution 3D imaging method.
