Deciphering structural complexity of brain, joint, and muscle tissues using Fourier ptychographic scattered light microscopy

VIEW, EarlyView.
This study introduces Fourier ptychographic scattered light microscopy (FP‐SLM). It combines Fourier ptychographic microscopy (FPM), which images large fields of view with high resolution, and computational scattered light imaging (ComSLI), which visualizes densely interwoven fibers.

Speckle Reduction in Digital Holography by Fast Logistic Adaptive Non-Local Means Filtering

Photonics
Digital holography is a promising imaging technology. However, there is speckle noise in the reconstructed image of a digital hologram. Speckle degrades the quality of the reconstructed image.

Wavefront division digital holography

AIP Advances, 2018
Digital holography (DH), mostly Mach-Zehnder configuration based, belongs to non-common path amplitude splitting interference imaging whose stability and fringe contrast are environmental sensitive.

Aerosol Measurements and Decadal Changes: The Role of Climatic Changes and How It Reflects in Respiratory Allergies and Asthma

Allergy, EarlyView.
ABSTRACT The causative agents of respiratory allergies are bioaerosols, such as house dust mite feces, pollen grains, and fungal spores. Climate change and urbanization are considered to lead to an increase in the load of allergenic bioaerosols due to impacts on plant phenophases and allergenicity. Continuous and efficient monitoring of the atmospheric

Direct Inversion of Digital 3D Fraunhofer Holography Maps

, 2015
The Differential Fourier Holography (DFH) gives an exact mathematical solution of the inverse problem of diffraction in the Fraunhofer regime. After the first publication [1] the Differential Fourier Holography was successfully applied in many ...

Real‐Time Rendering Framework for Holography

Computer Graphics Forum, EarlyView.
Abstract With the advent of holographic near‐eye displays, the need for rendering algorithms that output holograms instead of color images emerged. These holograms usually encode phase maps that alter the phase of coherent light sources such that images result from diffraction effects.

High‐Fidelity Computational Microscopy via Feature‐Domain Phase Retrieval

Advanced Science, Volume 12, Issue 21, June 5, 2025.
An innovative phase retrieval framework, termed FD‐PR, is uniquely established in the image's feature domain through the feature‐extracted, physical‐driven regression with interfaces for combining physics and image processing constraints. FD‐PR takes advantage of invariance components of an image against presences of model mismatch and uncertainty ...

Crack Detection by Optical Voice Recorder Based on Digital Holography

Photonic 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
