The operation of lasers in free space involves the potential risk of unintentionally exposing the human eye and skin to radiation. In addition to direct exposure, indirect scattered radiation of high-power lasers may pose a threat to operators, worki
Regulations of safety usage of hazardous substances impose companies to monitor their emissions. A novel approach determines the mass concentration of Cr(VI) in exhaust airflow based on angular light scattering combined with machine learning algorith

High power laser radiation scattered outside of the beam axis can be a potential threat. A novel detection system based on angular light scattering can help to access the risk of scattering by atmospheric particles.

Environmental Effects on Light Propagation and Adaptive Systems II.
Absorption and scattering by gaseous species, aerosol particles and precipitation lead to atmospheric attenuation of laser radiation. High power laser propagation over long horizontal and/or vertical distances is significantly affected by atmospheric

Environmental Effects on Light Propagation and Adaptive Systems.
Measurements of parameters of the natural atmospheric environment, like aerosol and precipitation distributions as well as the visibility, are simultaneously performed together with the angle dependent scattering of high power laser radiation. These
A numerical model is developed to simulate the angle dependent light scattering. The model is based on Mie theory and uses the complex refractive indices of aerosol particles and rain droplets together with their corresponding experimental number siz

Recent laboratory studies indicate that the hydrated form of crystalline NaCl is potentially important for atmospheric processes involving depositional ice nucleation on NaCl dihydrate particles under cirrus cloud conditions. However, recent experime
