Paper Abstract

An intrinsic multimode fiber-optic pressure sensor that is capable of measuring a specified range of dynamic (fast rise time) high-pressure impulses is discussed analytically and empirically. The sensor uses the pressure-induced microbend loss phenomena incurred by propagation modes of multimode fiber as its primary sensing mechanism and a pressure-induced refractive index change as a secondary effect. Several related variations of this fiber-optic pressure sensor are presented and compared in relation to their (1) pressure sensitivity, (2) ease of construction, (3) durability, and (4) environmental versatility. Two other measurement schemes are also discussed. Moreover, a high-impulse pressure-shock tube that is currently under construction will be discussed, along with a composite summary of the experimental results.
