Distributed Sensing of Single Mode Fibers with Correlation Techniques

Florian Azendorf, André Sandmann, Michael Eiselt +1

In this paper, we report on the development progress of correlation-based optical time domain reflectometry (OTDR). Substituting the direct detection receiver with a coherent recei…

Hollow-core fiber Characterization with Correlation-Optical Time Domain Reflectometry

Florian Azendorf, Bernhard Schmauss, Bo Shi +3

Using a Correlation-OTDR, we characterized the temperature-induced group delay variations of two nested antiresonant nodeless hollow core fibers. The temperature sensitivity of bot…

Position Measurement of Multiple Microparticles in Hollow-Core Photonic Crystal Fiber by Coherent Optical Frequency Domain Reflectometry

Jasper Podschus, Max Koeppel, Bernhard Schmauss +4

Flying particle sensors in hollow-core photonic crystal fibers require accurate localization of the optically trapped microparticles. We report position measurement to micrometer-r…

Fiber as a temperature sensor with portable Correlation-OTDR as interrogator

Florian Azendorf, Annika Dochhan, Florian Spinty +3

In this paper, we report on the integration of a Correlation-OTDR into a portable unit (30 cm x 30 cm), based on a multi-processor system on chip (MPSoC) and a small formfactor plu…
