Digital holographic microscopy enables the 3D reconstruction of volumetric samples from a single-snapshot hologram. However
unlike a conventional bright-field microscopy image
the quality of holographic reconstructions is compromised by interference fringes as a result of twin images and out-of-plane objects. Here
we demonstrate that cross-modality deep learning using a generative adversarial network (GAN) can endow holographic images of a sample volume with bright-field microscopy contrast
combining the volumetric imaging capability of holography with the speckle- and artifact-free image contrast of incoherent bright-field microscopy. We illustrate the performance of this "bright-field holography" method through the snapshot imaging of bioaerosols distributed in 3D
matching the artifact-free image contrast and axial sectioning performance of a high-NA bright-field microscope. This data-driven deep-learning-based imaging method bridges the contrast gap between coherent and incoherent imaging
and enables the snapshot 3D imaging of objects with bright-field contrast from a single hologram
benefiting from the wave-propagation framework of holography.
