“…1. As was shown earlier 8 , the use of the Raman effect and the Raman channel signal recording system makes it possible to carry out direct temperature measurements up to altitudes of 60-70 km with an error of 1-2 K. This circumstance indicates the adequacy of the recording method used for this signal level. The use of the lidar signal of molecular scattering is necessary to increase the altitude range of atmospheric temperature measurements up to 90-100 km.…”

The paper discusses the problem of ensuring the linearity of photo registration of the lidar signal of molecular scattering on the main lidar of the Siberian lidar station (SLS) based on a unique mirror with a diameter of 2.2 m. To reduce the dynamic range of signal changes, it is proposed to use a mechanical shutter based on a disk obturator to cut off the near zone of the lidar signal in the altitude range of 0÷30 km. A high-speed brushless motor was used as an obturator driver. The synchronization signal was generated by a Hall sensor. Bench and full-scale tests of the obturator were carried out. It is shown that the error of the Hall sensor does not affect the delay and duration of the shutter opening.

Показано, что определение значений порога дискриминатора для каждого модуля фотоэлектронного умножителя (ФЭУ)/канала счетчика фотонов позволит регистрировать лидарные сигналы в одинаковых условиях. Проведена стендовая апробация определения значений порогов дискриминатора счетчика фотонов «PHCOUNT4».
