Open AccessNon-convex optimization for inverse problem solving in computer-generated holography
Computer-generated holography is a promising technique that modulates user-defined wavefronts with digital holograms. Computing appropriate holograms with faithful reconstructions is not only a problem closely...

Open AccessQuantitative phase imaging based on holography: trends and new perspectives
In 1948, Dennis Gabor proposed the concept of holography, providing a pioneering solution to a quantitative description of the optical wavefront. After 75 years of development, holographic imaging has become a...

Open AccessDeep learning sheds new light on non-orthogonal optical multiplexing
A deep neural network for non-orthogonal input channel encoding is proposed to recover speckle images through a multimode fiber. This novel approach could shed new light on the non-orthogonal optical multiplex...

Open AccessDual-plane coupled phase retrieval for non-prior holographic imaging
Accurate depiction of waves in temporal and spatial is essential to the investigation of interactions between physical objects and waves. Digital holography (DH) can perform quantitative analysis of wave–matte...

Open AccessSingle-shot lensless imaging with fresnel zone aperture and incoherent illumination
Lensless imaging eliminates the need for geometric isomorphism between a scene and an image while allowing the construction of compact, lightweight imaging systems. However, a challenging inverse problem remai...
