Description

technical field

[0001] The invention relates to the technical field of atmospheric optics and fluid detection, in particular to a multifunctional atmospheric flow two-dimensional imaging detection device and detection method for atmospheric flow display and quantitative measurement. Background technique

[0002] The atmosphere is a transparent fluid that exists widely on the earth and is closely related to human survival and production activities. Atmospheric turbulence is an important form of motion in the atmosphere. Its existence significantly enhances the vertical and horizontal exchange of momentum, heat, water vapor, and pollutants in the atmosphere, which is far greater than the exchange intensity of molecular motion. The law of atmospheric turbulent motion is a scientific problem that is generally concerned by physics, meteorology, astronomy, and industrial and agricultural production but has not yet been fully resolved. It still needs to develop advanced measurement...
