Depth and Shape Estimation from Focus in Scanning Electron Microscope for Micromanipulation.
, 2013 International audienceInter-object depth estimation is always a major concern for micromanipulation using scanning electron microscope (SEM). So far, various methods have been proposed for estimating this depth based on stereoscopic imaging. Most of them

Advanced Photonics Research, Volume 6, Issue 7, July 2025.Optical wireless communications (OWCs) provide a promising alternative to spectrum‐congested microwave wireless communications. Recently, the use of metasurfaces with sub‐wavelength features for dynamic beam steering, beam manipulation, and spatial or optical‐angular‐momentum mode generation, conversion, and multiplexing in OWCs is proposed and ...

Passive Autofocusing System for a Thermal Camera
IEEE Access, 2020 Most of the Thermal (Infrared) cameras nowadays are equipped with a motorized lens for focusing a scene manually. The subjective nature of manual focusing makes it an inefficient and cumbersome process.

AutoSAFT: Autofocusing for extended depth of imaging in scanning acoustic microscopy
Journal of Microscopy, Volume 298, Issue 3, Page 283-292, June 2025.Abstract In the scanning acoustic microscopy (SAM) imaging, it is essential to address the diminished lateral resolution in the out‐of‐focus region, as image quality correlates with the ultrasound propagation distance either above or below the focal plane.

Nonparaxial propagation and the radiation forces of the chirped annular Bessel Gaussian beams
Results in Physics, 2020 We propose a new class of abruptly autofocusing beams, the chirped annular Bessel Gaussian beams (CABGBs), which are based on the radial Bessel profile.

Species‐specific diatom dynamics shape their vertical distribution and export during bloom decline
Limnology and Oceanography, Volume 70, Issue 4, Page 959-976, April 2025.Abstract The Southern Ocean is a critical region for global biogeochemical cycles, particularly for carbon dioxide uptake and organic carbon export, partly driven by extensive phytoplankton blooms. In naturally iron‐fertilized regions of this otherwise iron‐limited ocean, these blooms are primarily driven by diatoms. Variability in bloom occurrences on
