Free space optics (FSO)

Free space optical (FSO) communications systems are wireless point-to-point communications systems that use lasers to transmit and receive communication signals via line-of-sight directed laser beams. Known optical communication systems rely on optical fibers between transmitter and receiver. However, to establish a system network require obtaining right of ways and installation of fiber, a time consuming and expensive process. Free space optical communication systems are fundamentally different than fiber optic systems. Free space optical communication systems do not exhibit the limitations associated with the installation and maintenance of guided wave optical communication systems. Free space optics (FSO) use beams of light, such as laser beams, as optical communication signals, and therefore do not require cables or fibers connected between transmitters and receivers. Optical transmissions provide a wider bandwidth than other wireless communications mediums, such as RF frequency signals. Moreover, optical signals can generally be more focused than RF signals, and are thus more difficult to intercept and less likely to cause interference with other transmissions. FSO communication systems include optical transmitters and receivers that are configured to deliver and receive optical signals propagating in free space, and waveguides are not needed to connect the transmitter and receiver. The optical transmitter can modulate the optical signal to carry data. The optical receiver then collects all of the energy of the optical signal and converts the optical signal into an electrical signal. The optical receiver can operate on this electrical signal recover the modulated data and, in some applications, align the receiver to optimally receive the optical signal.
