Fiber Optic Rotary Joints (FORJs) are to optical signals what electrical slip rings are to electrical signals, a means to pass signals across rotating interfaces, particularly when transmitting large amounts of data. FORJs maintain the intrinsic advantages of fiber end to end.
A Fiber Optic Rotary Joint (FORJ) is a appliance that allows an optical pulse to be transferred across the
interface between a constant rotating platformand its stationary promote structure.
Moreover, known as optical rotary connectors or optical slip rings, FORJ applications have proliferated with the growing adoption of fiber optic communication conduction lines.
Such kind of applications as radar pedestals, wind turbines, armored vehicle turrets, and electro-optic sensors have incorporated fiber optic rotary joints to cope optical signals in parallel with slip rings to tackle electrical power and pulses. For the most part of these
applications use optical pulses to transport high speed digital data.
Yet, there are a few that depend on the FORJ to transport analog data with frequency or amplitude sensitive (i.e., analog) knowledge.
