Ecology and Evolution, Volume 15, Issue 8, August 2025.This study examined dorsal pattern variations across the geographic range of an Australian lizard using multispectral photography and visual models for lizards and avian predators. Findings reveal differences in dorsal colouration based on sex, body size, genetic clades and habitat type.

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.

Advanced Materials Interfaces, Volume 12, Issue 13, July 14, 2025.In this work, wide‐field (>1 mm2) frequency‐domain thermoreflectance (FDTR) hyperspectral imaging is used to image subsurface indium bump bonds 50 µm below the surface. Thermal analysis with Monte Carlo uncertainty propagation is used to evaluate bump quality, while a trained deep neural network (can rapidly reconstruct bump geometry contact area maps.

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.

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 ...

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.

CONTENT-BASED AUTOFOCUSING IN AUTOMATED MICROSCOPY
Image Analysis & Stereology, 2010 Autofocusing is the fundamental step when it comes to image acquisition and analysis with automated microscopy devices. Despite all efforts that have been put into developing a reliable autofocus system, recent methods still lack robustness towards different microscope modes and distracting artefacts.
