Advanced Materials Interfaces, Volume 12, Issue 9, May 5, 2025.Surface topographical deformation is enhanced in liquid crystal polymer/oligomer network coatings by integrating nonreactive liquid crystal 5CB as a plasticizer, which facilitates the creation of dynamic polymer‐based solid optical devices. Abstract Surfaces with dynamic topographies play a pivotal role in modern technology by providing adaptable ...

Holographic fluorescence microscopy with incoherent digital holographic adaptive optics
Journal of Biomedical Optics, 2015 Introduction of adaptive optics technology into astronomy and ophthalmology has made great contributions in these fields, allowing one to recover images blurred by atmospheric turbulence or aberrations of the eye. Similar adaptive optics improvement in microscopic imaging is also of interest to researchers using various techniques.

UmUTracker: A versatile MATLAB program for automated particle tracking of 2D light microscopy or 3D digital holography data [PDF]
, 2017 We present a versatile and fast MATLAB program (UmUTracker) that automatically detects and tracks particles by analyzing video sequences acquired by either light microscopy or digital in-line holographic microscopy. Our program detects the 2D lateral positions of particles with an algorithm based on the isosceles triangle transform, and reconstructs ...

Scatter Imaging using Digital Fourier Microscopy, Journal of Physics D:
Applied Physics 38 3590-3598 (2004), 2007 An approach reported recently by Alexandrov et al. on optical scatter imaging, termed digital Fourier microscopy (DFM), represents an adaptation of digital Fourier holography to selective imaging of biological matter. Holographic mode of recording of the sample optical scatter enables reconstruction of the sample image.

Automatic cross filtering for off-axis digital holographic microscopy
Results in Physics, 2020 Off-axis digital holographic microscopy (DHM) is a significant quantitative phase imaging (QPI) modality in a single shot. However, the reconstructed quality of the image in the off-axis DHM is governed by the spatial filtering in the spectral domain of ...
