Laser Communication system
[attachment=29824]
Advantages of Laser Communication Technology
Higher data rates
Compared to RF technology LC provides much higher data rates
Higher data rates are essential as more and more data is moved between diff. locations
High security regarding interception
A focused laser beam is hard to intercept without notice
Path to Quantum Cryptography
Advantages of LCS
Less frequency restrictions
RF spectrum is crowed and heavily used
Smaller aperture dimensions and thus reduced size and mass
Less weight and power per bit
Low cost communication
APPLICATIONS
At airports for communication across the runways
Defense and sensitive areas
Provide communication b/w satellite
Use weak signal modes for “cloud scatter
Transmit voice for miles line-of-sight
Conclusions
It established across the world can detect enemy ships & missile and at the same time disabling them
Two-way LC in space has become a goal for NASA
