Design Of A Pressure Sensor Of 0-7 Bar In Fiber Optic Using Mmi Methodology

This research shows the possibility of measuring pressure in the range of 0-7 bar and the comparison against 2 commercial sensors. The technique used is based on the multimodal interference in a fiber optic singlemode-multimode- singlemode (SMS) to 1550 nm. The fiber optic is mounted on a plate of stainless steel AISI 316, where the bending of the plate will generate a curvature on the part of the multimodal fiber generating a decoupling of modes and this generates a low intensity to the output of the system. © 2013 Elsevier GmbH.
