A device for determining the concentration of atmospheric aerosol in the stratosphere of the Earth in the altitude range from 10 to 40 km in the conditions of clouds with strong vertical development

摘要

The utility model relates to the field of meteorology and ecology. A device for determining the concentration of atmospheric aerosol in the Earth's stratosphere in the altitude range from 10 to 40 km in conditions of clouds with strong vertical development contains a pulsed source of infrared and blue emission spectra (1, 2) optically coupled to the first focusing optical element (9, 10), a photodetector (4) for recording light fluxes of backscattering by an aerosol of the atmosphere, optically coupled to a second focusing optical element (11), an amplifier for increasing the signal of backscattered light fluxes I, the power supply, and the pulsed radiation source consists of at least two LEDs (1, 2), and the photodetector (4) is a silicon photodiode, while the LEDs (1, 2) and the silicon photodiode (4) are installed in such a way that the angle between the optical axes of the focusing optical elements (9, 10 and 11) is from 4 to 6 degrees. The technical result is the expansion of the scope of use of the device. 2 ill.
