Wavelet-based analysis of cell dynamics measured by interference microscopy [PDF]

Компьютерные исследования и моделирование, 2009
Laser interference microscopy was used to study morphology and intracellular dynamics of erythrocytes, neurons and mast cells. We have found that changes of the local refractive index (RI) of cells have regular components that relate to the cooperative ...

Nanoscale surface characterization using laser interference microscopy [PDF]

Mechanics & Industry, 2017
Nanoscale surface characterization is one of the most significant parts of modern materials development and application. The modern microscopes are expensive and complicated tools, and its use for industrial tasks is limited due to laborious sample preparation, measurement procedures, and low operation speed.

Characterizing the Grating-like Nanostructures Formed on BaF₂ Surfaces Exposed to Extreme Ultraviolet Laser Radiation

Applied Sciences, 2022
Monocrystalline barium fluoride (BaF2) slab targets were irradiated by focused 46.9-nm laser radiation at various fluence levels above the ablation threshold. Well-developed ablation patterns with sharp edges were studied by AFM (atomic force microscopy).

Self-mixing interferometry and near-field nanoscopy in quantum cascade random lasers at terahertz frequencies

Nanophotonics, 2021
We demonstrate that electrically pumped random laser resonators, operating at terahertz (THz) frequencies, and comprising a quantum cascade laser heterostructure, can operate as sensitive photodetectors through the self-mixing effect.
