Modeling microcylinder-assisted conventional, interference and confocal microscopy [PDF]

EPJ Web of Conferences
We present how to develop virtual microcylinder- or microsphere-assisted surface topography measurement instruments. As the most critical part, the interaction between light, microcylinder and measurement object is considered based on the finite element ...

Digital holographic interference microscopy: physical method and algorithms of information processing

Вісник Харківського національногоуніверситету імені В.Н. Каразіна. Серія: Радіофізика та електроніка, 2022
Relevance. Interferometric methods for 3D visualization of micro-objects are highly non-invasive and non-contact. They can be used to obtain real-time information in the study of living and rapidly changing micro-objects.

Kinesin-propelled label-free microtubules imaged with interference reflection microscopy

New Journal of Physics, 2020
Interference reflection microscopy (IRM) utilizes the interference between the light reflected from the surface and the light reflected from an object to generate contrast and can be used to image nanometer size objects, such as a microtubule adhered to ...

White-Light Interference Microscopy Image Super-Resolution Using Generative Adversarial Networks

IEEE Access, 2020
To reduce external disturbances and achieve high vertical resolution, the scanning time for white-light interference microscopy is very short. Because capturing high-resolution (HR) images is time consuming, low-resolution (LR) images are acquired ...

Measuring Collagen Fibril Diameter with Differential Interference Contrast Microscopy

Journal of Structural Biology, 2021
Collagen fibrils, linear arrangements of collagen monomers, 20–500 nm in diameter, comprising hundreds of molecules in their cross-section, are the fundamental structural unit in a variety of load-bearing tissues such as tendons, ligaments, skin, cornea,

Effects of refractive index mismatch between sample and immersion medium in line-field confocal optical coherence tomography

Journal of the European Optical Society-Rapid Publications
Line-field confocal optical coherence tomography (LC-OCT) is an optical technique based on low-coherence interference microscopy with line illumination, designed for tomographic imaging of semi-transparent samples with micrometer-scale spatial resolution.

Scanning interference microscopy [PDF]

Bioimaging, 1994
We consider the form of the interference term image in scanning interference microscopes employing finite sized coherent and incoherent detectors. We show, inter alia, that for the case of incoherent photodetectors the interference term image in scanning confocal and scanning conventional systems behave identically in all respects including optical ...

Hybrid scanning electrochemical cell microscopy-interference reflection microscopy (SECCM-IRM): tracking phase formation on surfaces in small volumes.

Faraday discussions, 2021
We describe the combination of scanning electrochemical cell microscopy (SECCM) and interference reflection microscopy (IRM) to produce a compelling technique for the study of interfacial processes and to track the SECCM meniscus status in real-time ...

Organoids in pediatric cancer research

FEBS Letters, EarlyView.
Organoid technology has revolutionized cancer research, yet its application in pediatric oncology remains limited. Recent advances have enabled the development of pediatric tumor organoids, offering new insights into disease biology, treatment response, and interactions with the tumor microenvironment.
