The Analysis Of Transmitted Image Compression Technology Based On Laser Communication

The laser digital image communication is one of the way in which the information is transmitted on the channel of space with the laser beam . This kind of communication way has the characteristics of heavy capacity, strong anti-interference, high dependability, high security. Therefore, the laser digital image communication is applied prospectly in the field of military, national defence , civil aspect.The paper has deeply research on the basic theory of image compression and coding , atmosphere absorption, atmosphere scattering , atmospheric turbulence and back light which have great influence on image transmission quality on the basis of overall design of the laser digital image communication . The paper has carried on a more thorough study on the video signal compression and coding. Meanwhile the application to datum transmission is deeply studied. The paper designs hardware circuit based on MPEG-2 standard and datum reapplication. In the end the experimental result is offered.
