High Performance Fiber Optic Rotary Joint System

Agiltron proposes to develop a new class of multi-channel FORJ, which meets the demanding aerospace communication rotary link requirement of ultra-reliability, light weight, compact size, and high performance. Our approach is based on an optical wavelength division multiplexing (WDM) platform which enables a single light beam to carry multi-channel signals and pass through the rotary joint. The unique design offers unmatched ultra-high reliability and miniature size due to single optical rotation axial coupling construction. The proposed miniature FORJ is well suited for retrofitting into many existing installations such as folding airplane wings, radar antennas, turrets and winches. The simple design is compatible to mass production process and has intrinsic mechanism to assure continuous optical connection of multi-port during rotation in severe shock, vibration and thermal environments. Phase I work will demonstrate the compact fiber optic rotary joint by building a working prototype. Phase II will produce a full specification working system.
