Method for quantitatively calculating optical observation light pollution

Abstract

The invention provides a method for quantitatively calculating optical observation light pollution. The method comprises the following steps: establishing a yellow channel light semaphore simulation model, an air glow semaphore simulation model, a galaxy light semaphore simulation model and an atmospheric scattering light semaphore simulation model; performing actual observation by using an optical telescope to obtain a night-sky light observation semaphore; carrying out simulation calculation by utilizing the established simulation model to obtain a yellow channel optical semaphore, an airglow semaphore, a silver river system optical semaphore and an atmospheric scattered light semaphore; summing and calculating according to the obtained semaphore of the night-sky light component to obtain a night-sky light semaphore; and calculating the difference between the night-sky light observation semaphore obtained by the optical telescope and the night-sky light semaphore obtained by simulation calculation to obtain the light pollution observation semaphore. According to the method, quantitative calculation of the light pollution observation semaphore is achieved, large errors caused by analyzing light pollution through data observed by observation equipment are avoided, and initial site selection of the observatory and analysis and research in the optical observation process are facilitated.

Description

technical field [0001] The invention relates to the technical field of optical telescopes, in particular to a method for quantitatively calculating light pollution in optical observation. Background technique [0002] Human space activities have produced a large amount of space debris, and the establishment of the observatory provides conditions for the observation of space debris. But nowadays, light pollution is serious, and the site selection of the observatory and the analysis and research of optical observations are greatly affected by light pollution. Therefore, it is necessary to study light pollution. [0003] At present, for the analysis and research of light pollution, some researchers mainly use all-sky cameras, high-resolution satellites, high-resolution spectrometers, etc. to observe the brightness of the night sky, so as to obtain observation data, and analyze light pollution according to the observation data; Some researchers use optical telescopes to adjust ...

AI Technical Summary

Problems solved by technology

[0004] However, since light pollution is an integral part of night sky light, analyzing light pollution only through the night sky brightness data observed by observation equipment has a large error with the real result, which is not conducive to the initial site selection of the observatory, and is also not conducive to the analysis and research in the process of optical observation
