Paper Abstract

The use of low frequency (sub 20 MHz) incoherent optical frequency domain reflectometry (IOFDR) provides a low cost alternative to the conventional OTDR techniques often used in the interrogation of optical fiber microbend sensors. We have modeled the operation of the IOFDR and experimentally characterized the operation of this technique for monitoring distributed water sensors based on water-swellable polymers (hydrogels). We demonstrate that the IOFDR is capable of detecting and locating sections of increased loss in a graded index multimode optical fiber and discuss the fundamental limits on spatial resolution and range.
