Lensless single-shot dual-wavelength digital holography with sub-pixel resolution and centimeter depth range [PDF]

APL Photonics
Lensless single-shot dual-wavelength digital holography is resolution limited by the pixel-size of the camera and often has an insufficient depth range.

Seeing the invisible: Digital holography

European Mathematical Society Magazine, 2022
For the past years there has been an increasing interest in developing mathematical and computational methods for digital holography. Holographic techniques furnish noninvasive tools for high-speed 3D live cell imaging. Holograms can be recorded in the millisecond or microsecond range without damaging samples.

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

Molecules
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 ...
