Strain and temperature sensitivity measurement using simple microstructured fiber Mach-Zhender interferometer

Abstract

In this paper we present the experimental comparison of mechanical and temperature sensitivities of Mach-Zehnder interferometer with replaceable FC connectorized sensing fibre arm, such as: off-the-shelf endlessly single mode microstructured fibre (MSF) or standard telecom single mode fibre. Experimental results clearly show reduced crosssensitivity to temperature of studied MSF compared with standard doped core fibre. Additionally, microstructured fibre Mach-Zehnder interferometer with standard FC receptacles allows using different fibres as sensors with the same device. Moreover, investigated interferometer consumes in total extremely low electric power (< 20 mW) and VCSEL as the light source.

Nanoporous nanocrystalline monoclinic zirconia for luminescent oxygen sensors

“…The density of the annealed nanopowder was measured by means of helium picnometry using a AccuPyc 1330, produced by Micrometrics Instruments. High density, ~5,9 g/cm 3 , of nanopowder indicate its good quality with a high degree of crystallinity what is illustrated in Figure 2. …”

“…At the same time, tremendous attention was focused on fiber optic sensors, FOS, (including Microstructured Optical Fibers, MOF), due to their remarkable properties. These materials have revolutionized a multitude of various sensing applications [2,3], including sensing in harsh environments [4]. Therefore, they are appreciated by the industry, since it is predicted that the FOS market will surpass 2.5 billion USD in 2017 [5].…”
