Abstract

Laser communications offer a viable alternative to RF communications where High data rate, small antenna size, narrow beam divergence, and a narrow field of view are characteristics of laser communication that offer a number of potential advantages for system design. The high data rate and large information throughput available with laser communications are many times greater than in radio frequency (RF) systems. The small antenna size requires only a small increase in the weight and volume of host vehicle. The implementation of data and audio transmission with laser as a medium is aimed at exploring the use of laser technology for efficient and secure communication. This project involves designing a laser communication that can transmit digital data and audio signals over long distances. The system is comprised of a laser diode, a modulator circuit, and a photodiode receiver, which work together to convert the input data into modulated laser pulses that are transmitted through the atmosphere. The receiving end of the system uses a photodiode receiver to detect the laser pulses and convert them back into digital data and audio signals. This focus on the design, construction, and testing of the laser communication system, including the use of various modulation techniques to improve the quality and reliability of the transmission.
