Laser communication has the potential to send much more information at once than radio-based communication, creating the possibility that astronauts could one day stream hd video across the solar system. Laser communication system works on the principle of “amplitude modulation” process in this the amplitude of the carrier is varied according to the instantaneous amplitude of the modulating signal (input signal ). Laser based communication system contents • introduction • implementation • working • working model • applications • advantages.
Laser communication system circuit diagram the circuit module consists of a transmitter and also a receiver which use ic lm386 it is powered by a 9v battery. We have simulated a speckle optimization scenario with typical parameters for a laser communication system over a long horizontal path length the results of these simulations show that even with a modest number of phase modulators it is possible to very significantly reduce the occurrence of deep fades.
