The single-mode POF sensors were unmounted and surface mounted on aluminum tensile coupons for strain measurements. The measured strains from the POF sensors were compared to extensometer measurements for validation. The phase response of the interferometer was measured with a 3 × 3 coupler interrogator. The coupler arrangement was configured to permit the extraction of potential intensity changes in the sensor arm. The phase-shift–strain response of the POF sensors was repeatable for the loading and unloading measurements. The nonlinearity of the phase-shift–strain response was greater than that measured during pure tensile loading of the POF, presumably due to the behavior of the adhesive between the optical fiber and the aluminum coupons.}, number={7}, journal={MEASUREMENT SCIENCE AND TECHNOLOGY}, author={Abdi, Omid and Peters, Kara and Kowalsky, Mervyn and Hassan, Tasnim}, year={2011}, month={Jul} }
 @article{abdi_wong_hassan_peters_kowalsky_2009, title={Cleaving of solid single mode polymer optical fiber for strain sensor applications}, volume={282}, ISSN={["1873-0310"]}, DOI={10.1016/j.optcom.2008.11.046}, abstractNote={Abstract Single mode polymer optical fibers (smPOFs) can be applied for measuring large strains in numerous applications, such as civil engineering infrastructure assessment and health monitoring. Because of the large light attenuation of solid smPOFs, small lengths of the fiber would need to be coupled to silica optical fibers (SOFs) for practical applications of the smPOF as a strain sensor. This coupling requires smooth cleaving of the smPOFs. In this work, several cleaving techniques previously demonstrated to provide smooth cross-sections of multimode POFs were applied to the smPOF. From these techniques, hot-knife cutting was determined to be a feasible method for cleaving when the blade was heated to 80 °C and the smPOF heated in the range of 30 °C to 40 °C. In addition, focused ion beam machining which produces high-precision cleaves of the solid smPOF cross-section, was performed to set a bench mark and thus evaluate the quality of cleaving from other methods used in this study.}, number={5}, journal={OPTICS COMMUNICATIONS}, author={Abdi, O. and Wong, K.
