Fourier transform holography at the wavelength limit

open access: yes, 2022
Paper DTh2E.4We present a table-top Fourier transform holography experiment that achieved a record-high resolution of 34 nm. By employing phase retrieval techniques, the resolution was improved to 23 nm (

Crack Detection by Optical Voice Recorder Based on Digital Holography

open access: yesPhotonic Sensors, 2019
The detection of crack on materials is an important issue in industry. On the contrary to conventional methods, such as manual inspection, sensor detection, and image processing techniques, a new simple method to detect the crack is proposed with optical

Identification and Size Estimation of Non-Spherical Nanoparticles using Polarization-Resolved Holography

open access: yes, 2020
Dual-view polarization-resolved digital holography is used to record the polarization response of the scattered light from both spherical and non-spherical nanoparticles. A model based on the T-matrix method is developed to map the polarization to a size

In Situ Holographic Monitoring of Stress Corrosion Dynamics of Alloy 625 in Cl + S2O32− Solution

open access: yesMolecules
This study examined the stress corrosion of Alloy 625 in Cl− + S2O32− solutions using digital holography in combination with electrochemical methods. Without elastic tensile stress, intergranular corrosion (IGC) occurred, due to the higher activity of ...
