Paper Abstract

We have interrogated a commercially available (SOFO) fiber optic displacement sensor in a dynamic mode using microwave sub-carrier interferometry. The detection threshold is in the region of 50 nm and the linear dynamic range extends to several centimeters using a sub-carrier frequency around 900 MHz.
