AutoSAFT: Autofocusing for extended depth of imaging in scanning acoustic microscopy

open access: yesJournal 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.

Digital holography - an innovative technology for analysis of living cells

open access: yesBioingeniøren, 2010
Background: Digital holography is a novel technique which has been used for about five years to study living cells. The technique is an innovative, non-destructive method with possibilities to study living cells over time.

Spatiotemporal heterodyne detection

open access: yes, 2007
We describe a scheme into which a camera is turned into an efficient tunable frequency filter of a few Hertz bandwidth in an off-axis, heterodyne optical mixing configuration, enabling to perform parallel, high-resolution coherent spectral imaging.

Deep learning bimodal frequency-selective digital holography by using a confocal dual-beam setup

open access: yesNew Journal of Physics
This paper proposes a bimodal digital holography technique based on deep learning, marking the first application of neural networks in frequency-selective holographic reconstruction.

Strain Measurement Using Phase-shifting Digital Holography with Two Cameras

open access: yesEPJ Web of Conferences, 2010
Phase-shifting digital holography is a convenient method to measure displacement and strain distributions. Development of compact and conventional strain distribution measurement equipment for practical use is required for inspection of health monitoring

Movies of cellular and sub-cellular motion by digital holographic microscopy

open access: yesBioMedical Engineering OnLine, 2006
Background Many biological specimens, such as living cells and their intracellular components, often exhibit very little amplitude contrast, making it difficult for conventional bright field microscopes to distinguish them from their surroundings.
