It is inevitable that Fibre Optics for data transmission and sensing will play a key role in future control systems for aerospace mobile platforms. It is important that the practical requirements for sensing/instrumentation in aerospace systems are well understood. Displacement sensing is a primary parameter and Wavelength Division Multiplex (WDM) digital optical encoding schemes offer a very attractive design solution.
