title = "Simultaneous Interrogation of Multiple Tapered Fiber Optic Sensors by Interferometric Illumination",
abstract = "Tapered Fiber Optic Sensors (TFOS) are typically interrogated using an Optical Spectrum Analyzer (OSA) or a spectrometer. As a result, multiple TFOS with similar operating wavelengths cannot be interrogated simultaneously. This paper is an extension to the previously published work on 'Interrogation of Fiber Bragg Grating Arrays by Illumination using a Low Coherence Interferogram' [1]. In this paper, the ability of the system to simultaneously interrogate multiple TFOS in a single interferometric scan is demonstrated. Varying concentrations of glucose solutions were used to determine the system's sensing capability. Of the two TFOS used, the one with the larger FSR was found to yield a linear resolution of \mathbf{\sim 2.96\mathbf{e}-3\Delta \mathrm{Rad}/1000\mathbf{ppm}} and the other sensor with a smaller FSR yielded a linear resolution of \mathbf{\sim 5.23\mathbf{e}-3\Delta \mathbf{Rad}/1000\mathbf{ppm}}.",
