Underwater Acoustic and Visible Light Communication for Naval Submarines

This project is a remittance to the existing system where we have come up with an idea of combining laser waves and acoustic waves. We all know that light and sound can be used for data transmission through air. We have implemented an advancement for technology by using these waves underwater for the communication of naval submarines. The LASER BEAM (blue laser or green laser(450nm to 532 nm) can be used as a light source to transmit data from the Submarine underwater to the base station or satellite as green laser tends to look much brighter than red laser. Also, green light bends more than red when it enters glass lens. Since laser cannot penetrate through some objects we wanted to overcome that deprivation using acoustics which was previously existing .As laser is Omni directional there wouldn’t be any parsing of the data. This method can be used to overcome errors which are occurring during maximum transmission rate in existing system and it is more efficient. This bypasses the limitations involved in the use of electromagnetic waves and acoustic waves for underwater communication.
