Abstract

A new method of developing optical fiber pressure sensors by use of a fiber loop ringdown scheme is described. The fiber loop ringdown system is characterized in terms of the ringdown baseline stability, fiber transmission loss, and fiber refractive index. The overall sensor performance is demonstrated by use of sensing forces applied to the sensor head. The current device can sense pressures in the range of 0 to 9.8 × 10<sup>6</sup> Pa, converted approximately from the applied forces. The sensor’s linear response, repeatability, detection sensitivity, measuring dynamic range, and temperature tolerance are explored.
