Intelligent Plasmonic Bio‐Holoelectrochemical Systems: A Testable Architecture for Light‐Programmed Microbial Electrochemistry

open access: yesGlobal Challenges, Volume 10, Issue 9, September 2026.
An evidence‐derived architecture integrates structured light, plasmonic bioelectrodes, spatial sensing, microbial electrosynthesis, and digital‐twin control into a testable framework for light‐programmed microbial electrochemistry. Mechanistic discrimination, equal‐dose spatial validation, and conservation‐aware performance accounting define the ...

Phase Retrieval for Digital Holographic Microscopy With Defocused Holograms

open access: yesIEEE Photonics Journal, 2018
A new phase retrieval technique in digital holographic microscopy (DHM) with three defocused holograms is proposed. Given the defocusing distance, the phase distributions of tested specimen can be reconstructed with a simple algebraic equation.

Giant phytoplankton revealed by in situ imaging

open access: yesLimnology and Oceanography Letters, Volume 11, Issue 5, September 2026.
Abstract Deployment of an autonomous Zooglider in the western Mediterranean Sea revealed the presence of long phytoplankton chains attaining maximum lengths of 6.4–10.4 mm suspended in situ. Elongate chains included the diatoms Guinardia, Proboscia, two other diatom morphologies, and solitary filaments of the cyanobacterium Trichodesmium. Most elongate

Special Issue on Digital Holographic 3D Imaging: Capture, Display, and Evaluation

open access: yesETRI Journal, 2019
Holography has been fascinating people for almost 70 years (since Gabor's invention in 1947) as a true three‐dimensional (3D) imaging technology that can replicate 3D scenes in free space.

Microsphere-assisted quantitative phase microscopy: a review

open access: yesLight: Advanced Manufacturing
Light microscopes are the most widely used devices in life and material sciences that allow the study of the interaction of light with matter at a resolution better than that of the naked eye. Conventional microscopes translate the spatial differences in

Fast and robust diffraction based overlay metrology using dark-field digital holographic microscopy

open access: yes, 2021
Digital holographic microscopy allows access to the complex electric field, enabling computational propagation of light. This enables computational corrections for lens aberrations, which remove the requirement for antireflective coatings on the lens and

Computational coherent superposition self-reference digital holographic microscopy for multiwavelength 3D information acquisition

open access: yesJPhys Photonics
I propose a digital holographic microscopy technique in which complex amplitude distributions at multiple wavelengths are simultaneously obtained with a common-path self-reference interferometer and a monochrome image sensor.

Separation of overlapped particles in digital holographic microscopy

open access: yesOptics Express, 2013
In this paper, we present a procedure to separate aggregates of overlapped particles in digital holograms, based on a focus plane analysis applied to each particle. The method can be applied either on phase or on amplitude objects, according that each object has a border in one focus plane. Numerical simulations are performed to quantify the robustness
