The Study for Laser Beam Transmission Character in Atmosphere Rondom Channer by Using CCD

Some effects that affect the transmission in atmosphere of laser signals are introduced.Some phenomena,such as the absorption,dispersion and onflow of aerosol,dust,frog,rain and haze,are engendere by the interaction of laser and atmosphere when the former goes through the latter.These all will produce some other effects that would strongly affect the transmission of laser signals,especially attenuation,coruscation and dithering of beam.They can be experimentally validated through a set of device besides CCD that can shoot and analyze the images of laser signals on conditions of different visidility,atmosphere and time.
