Generating Multi‐Depth 3D Holograms Using a Fully Convolutional Neural Network
Advanced Science, Volume 11, Issue 28, July 24, 2024.This work introduces the forward–backward‐diffraction framework for computing multi‐depth diffraction fields and the layer‐by‐layer replacement method for handling occlusion relationships. When combined with a fully convolutional neural network, it generates multi‐depth holograms with excellent depth focusing and corrects occlusion relationships.

Stochastic Assessment of Dissolution at Fluid‐Mineral Interfaces
Geophysical Research Letters, Volume 51, Issue 7, 16 April 2024.Abstract Chemical weathering associated with dissolution/precipitation at interfaces between minerals and flowing fluids is key for the evolution of geologic systems, including groundwater contamination and storage capacity. Relying on Atomic Force Microscopy (AFM) yields reaction rates at nanoscale resolutions.

Digital three-color holographic interferometry for flow analysis
Optics Express, 2008 A digital three-color holographic interferometer was designed to analyze the variations in refractive index induced by a candle flame. Color holograms are generated and recorded with a three layer photodiode stack sensor allowing a simultaneous recording with a high spatial resolution.

Spontaneous Transition of Spherical Coacervate to Vesicle‐Like Compartment
Advanced Science, Volume 11, Issue 7, February 16, 2024.This study shows the formation of a coacervation‐driven membrane‐less vesicle‐like structure using GG1234 and bhBMP‐2. A phase transition from spherical simple coacervates to vesicular condensates occurred upon the addition of bhBMP‐2 to GG1234 simple coacervates under acidic conditions, eventually leading to multiphasic vesicle‐like compartments with ...

Information retrieval from holographic interferograms: Fundamentals and problems [PDF]
Holographic interferograms can contain large amounts of information about flow and temperature fields. Their information content can be very high because they can be viewed from many different directions. This multidirectionality, and fringe localization

Holographic recording of fast events on a CCD camera [PDF]
, 2002 We report on holographic recording of nanosecond events on a conventional CCD camera. Three frames of an air-discharge event, with resolution of 5.9 ns and frame interval of 12 ns, are recorded in a single CCD frame.
