Structured illumination lensless digital holographic microscopy (SI-LDHM)
In this work, we propose a structured-illumination lensless digital holographic microscopy (SI-LDHM). SI-LDHM illuminates a sample with 24 structured illuminations (8 orientations × 3 phase shifts) and records the defocused interferogram formed by two ...

Ultrasound Mediated Cellular Deflection Results in Cellular Depolarization
Ultrasound has been used to manipulate cells in both humans and animal models. While intramembrane cavitation and lipid clustering have been suggested as likely mechanisms, they lack experimental evidence. Here, high‐speed digital holographic microscopy (

Object Plane Detection and Phase Retrieval from Single-Shot Holograms using Multi-Wavelength In-Line Holograph [PDF]
Phase retrieval and the twin-image problem in digital in-line holographic microscopy can be resolved by iterative reconstruction routines. However, recovering the phase properties of an object in a hologram needs an object plane to be chosen correctly for reconstruction.

Variable zoom digital in-line holographic microscopy
We report on a novel layout providing variable zoom in digital in-line holographic microscopy (VZ-DIHM). The implementation is in virtue of an electrically tunable lens (ETL) which enables to slightly shift the illumination source axial position without mechanical movement of any system component.
