Research On The Technology Of The Atmosphere Laser Signal Based On ARM Microprocessor

Atmospheric laser communication is a atmospheric optical communication systems that is carried by laser light, and transmiss in atmospheric.In the atmosphere laser communication, as a result of atmospheric scattering, absorption , atmospheric onflow and so on, and will bring facula vibration, signal phasic undulation and so on in the receiving end, therefore needs to study one kind of method to suit the processes under the high speed, the weak signal condition, and guarantee the error rate of laser signal.This investigates one kind of atmosphere laser signal processing method on the embedded microprocessor system.The paper starts from the development of space laser and the air channel environments,adopts the ARM controller micro and transplants the real-time operating systemμC/OS-II on the controller, using the fluctuation threshold value algorithm to minish the infection of the channel of the atmosphere.And taking more effect in the testing.
