摘要
Due to weather and environment problems, different scientists have been studied atmospheric turbulence by focusing on a model for vertical atmospheric turbulence for practical applications like stellar imaging. For studying the atmospheric behavior horizontally, we used a laser beam that is propagated in a horizontal path at a laboratory room scale and an Optical Turbulence Generator OTG, inserted along the optical path. The airspeed was controlled inside the OTG and some physical variables like temperature and relative humidity were measured for verifying their effects on the local atmosphere. The experimental results show these effects over the angle structure function, the laser beam centroid shifting, and the statistical measurements by using imaging processing which are important to model oneself on environment conditions in an open field.
