Title: | Fiber-optic in-line Mach-Zehnder modal interferometer for breathing monitoring application | Authors: | Wang, K Xu, W Zhang, N Li, K Yu, C Yu, C |
Issue Date: | 2017 | Source: | In Proceedings of 2017 Conference on Lasers and Electro-Optics Pacific Rim (CLEO-PR), 31 July 2017 - 04 August 2017, Singapore | Abstract: | A simple fiber-optic in-line Mach-Zehnder modal interferometer is fabricated and studied for monitoring human being's breathing rate, which is one of the most important vital signs. The sensing structure is simply fabricated by a couple of up-tapers manufactured in the common telecommunication single mode fiber (SMF) by a commercial splicer. Sensing performances with different distances between the dual uptapers are addressed. The whole setup only contains one laser source, one photo-detector and one section of SMF with dual up-tapers. It can real-timely monitor people's respiration rhythm without complex signal processing and the scheme is simple and low-cost. | Keywords: | Breathing monitoring Mach-Zehnder Modal interferometer Optical fiber sensor |
