Real Time Implementation of Secured Video Transmission over Free Space Optics

Free space optics (FSO) is a line-of-sight technology that currently enables optical transmission up to 2.5 Gbps of data, voice, and video communications through the air , allowing optical connectivity without deploying fiber optic cables or securing spectrum licenses. FSO system can carry full duplex data at giga bits per second rates over Metropolitan distances of a few city blocks of few kms. FSO, also known as optical wireless, overcomes this last-mile access bottleneck by sending high –bitrate signals through the air using laser transmission. The security of video data is necessary in video transmission for military purpose and other applications. In this project capable to transmitting sound signals through a laser beam is proposed. Video transmission from one sender to other should be in secure way. The main purpose of this paper is too important for the efficient data transfer of the data and to maintain the secrecy of the data that is to be transmitted. From the past time to present time security of confidential information is always an important issue.
