Skin cancer screening – better safe than sorry [PDF]
SHS Web of Conferences, 2020 Skin cancer is the most common type of cancers. In Latvia, on average there are approximately 200 new melanoma and 1300 non-melanoma cancer cases per year. Non-melanoma cancers are: Basal Cell Carcinoma, Squamous Cell Carcinoma and others.

Wavelength Sensing Based on Whispering Gallery Mode Mapping
Fibers, 2022 We demonstrate a wavelength sensor based on whispering gallery mode (WGM) resonators. For the first time, multiple polymethyl methacrylate (PMMA) microspheres were simultaneously attached to a tapered fiber.

Spectral Line Reflectance and Fluorescence Imaging Device for Skin Diagnostics
Applied Sciences, 2020 The multi-spectral-line imaging concept, which was recently implemented for the snapshot mapping of three main skin chromophores—melanin, oxy-hemoglobin, and deoxy-hemoglobin, is further explored for the snapshot capturing of four spectral line images at

Phonon Spectroscopy at Atomic Resolution [PDF]
Physical Review Letters, 2019 Advances in source monochromation in transmission electron microscopy have opened up new possibilities for investigations of condensed matter using the phonon-loss sector of the energy-loss spectrum. Here, we explore the spatial variations of the spectrum as an atomic-sized probe is scanned across a thin flake of hexagonal boron nitride. We demonstrate

Three-dimensional Analyses of Geological Materials on Nanoscale by Electron Tomography
, 2022 Electron tomography (ET), an electron-microscopy-based technique that provides three-dimensional (3D) structural information from a tilt series of two-dimensional (2D) projections, has promoted the in-depth investigation of biological molecules in ...

SkImager: a concept device for in-vivo skin assessment by multimodal imaging; pp. 301–308 [PDF]
Proceedings of the Estonian Academy of Sciences, 2014 A compact prototype device for diagnostic imaging of skin has been developed and tested. Polarized LED light at several spectral regions is used for illumination, and round skin spot of diameter 34Â mm or 11Â mm is imaged by a CMOS sensor via cross ...
