Abstract

Many advanced systems such as next generation aircraft and automated factories require highly reliable, precise control functions. The designers of these systems are specifying fiber optics for not only interconnecting the sensors and actuators to the control circuits but also providing a passive (i.e. no electrical power) sensor mechanism. Optical sensors that have been developed can provide high sensitivity, EMI/EMP immunity, light weight, high reliability, low cost, and a single fiber for input and output of signals.
