Optical Communications
Optical Communications is a field of study that deals with the transmission of information using light as a carrier. It involves the use of optical fibers, lasers, and other optical devices to transmit data over long distances with high bandwidth and low loss. Optical Communications is widely used in space and astronautical engineering for communication between spacecraft and ground stations, as well as between different spacecraft in space. It is also used for remote sensing and imaging applications, such as Earth observation and planetary exploration. Optical Communications has several advantages over traditional radio frequency (RF) communications, including higher data rates, lower power consumption, and greater security. However, it also has some challenges, such as susceptibility to atmospheric disturbances and the need for precise pointing and tracking of the optical beam.
