Abstract
The main results of investigations of energy and time characteristics of laser pulse transmission in the range from 0.36 to 1.55 mm along horizontal and inclined mountain paths with lengths from 0.05 to 8.5 km at altitudes from 1100 to 2100 m at ILP SB RAS research site “Kaitanak" in the Altai Mountains are presented. The characteristics of optical interference in the UV- A range at different altitudes were measured. Experimental estimates of optical signals reception in the range of 0.36 mm and 0.45 mm by UAVs at a distance of up to 1.5 km from ground-based laser emitters are obtained. The parameters of retroreflectors for laser signals after operation for several years at remote mountain posts are given. The totality of the obtained characteristics opens new possibilities of building laser environmental monitoring systems for remote control of dangerous deformations of mountain slopes and rockfalls, snow accumulation, and occurrence of fires, storms, etc.
