Subject of study. This study investigated the spatial-spectral distortions arising from acousto-optic diffraction, which must be considered when constructing an optical system and calibrating acousto-optical device. Aim aimed to perform spatial spectral calibration imaging spectrometers based on tunable filters develop a technique for equalizing transmittance filter in entire working range. Method. To obtain undistorted data, both inhomogeneities need corrected. The procedure consisted...
The paper presents a small-sized acousto-optic imaging spectrometer. spectrometer operates in the Vis-NIR spectral ranges $(0.45-0.85 \mu \mathrm{m})$. Its optical and technical characteristics are presented, design features described. developed has high image quality acceptable aperture ratio, which sufficient for most applications scientific research. A method correcting recorded depending on changes illumination of investigating objects is proposed. This technique based use graduation...
Subject of study. This study focuses on methods for designing optical schemes acousto-optical (AO) hyperspectral devices tailored applied problems. Aim The objective is to develop a device incorporating tandem AO tunable filter the 0.85–1.6 µm spectral range. Method. system was designed using Zemax, supported by an original software module. simulation outcomes were experimentally verified. Main results. A short-wave infrared and manufactured. employs InGaAs sensor uses filtration enhance...
The cold stress is one of the main functional tests in study microvascular bed skin.An important task to automate visualization capillary network and measurement microcirculation parameters directly local area inflammation.In this paper, we describe a system developed for non-invasive processing such images order determine morphological their changes under external conditions.Proposed approach provides high-quality skin microvessels allows obtaining reliable information about map.The results...
