Simultaneous observations of fast optical events in the Earth's atmosphere by optical devices complex

摘要

The work continues the research started in 2017. In 2018 in addition to constant monitoring of the night sky glow, a series of experiments were carried out to register fast variations in the spatial intensity distribution of the night sky radiation in the spectral range of 400-900 nm by an optical instruments complex. The devices complex includes: A photometer assembled on the basis of SONY ICX285AL CCD matrix and a high-aperture lens Jupiter 3; Highly sensitive optical system created on the basis of the 3rd generation EPM102G-04-22C electron-optical converter (EOC) and the Baumer HXG40NIR camera based on CMOSIS CMV4000 1 matrix; Fast four-channel photometer with sensors based on silicon photomultipliers. The paper presents the results of experiments on the synchronous observation of fast optical phenomena in the Earth's atmosphere. The number of events recorded simultaneously on multiple devices is given. We describe methods and algorithms for extracting events from data series.
