Abstract

Fiber optic sensing technology has now reached the point at which it is mature enough to be applied to practical aerospace applications. In particular, closed loop control of flight surfaces in which the sensor continuously monitors actuator position in order to provide feedback to the control system is of interest. In this paper, we describe the principle of operation, design and preliminary testing of a long stroke length (20 cm, 7.8 inches) wavelength encoding multimode fiber optic linear position sensor. The sensor provides a significant reduction in size over conventional LVDT sensors for the same application.
