Laser for Atmospheric Exploration
Atmospheric Exploration is a method of measuring distance. It irradiates the target with a pulse Laser and measures the reflected pulse with a sensor.Different laser return time and wavelength can be used to make digital 3d representation of the target.The atmospheric exploration is now used for light detection and ranging. Atmospheric exploration is sometimes called 3d laser scanning, which is a special combination of 3d scanning and laser scanning.It has ground, air and mobile applications.
Laser is commonly used to make high-resolution maps and has applications in geodesy, geology, archaeology, geography, geology, geomorphology, seismology, forestry, atmospheric physics, and laser surveying.The technology is also used to control and navigate some self-driving cars.

Applications:
1.System of detecing Aerosol
The absorption and scattering of Aerosols to sunlight will greatly
change the atmosphere system. Aerosol testing provides important
data to the study of global warming and pollution of the environment.
CNI provides lasers for the system of detecting Aerosol based
on Mie scattering theory.
2. System of detecting the atmospheric temperature
Detection of atmospheric temperature is important to the analysis
atmospheric dynamics. At present, the method of measuring middle
by lidar is very effective.
CNI provides lasers for detection system of the atmospheric
of weather forecasting, atmospheric environment and process of
atmosphere temperature is rare, so observing stratospheric temperature
temperature based on Rayleigh scattering theory.
