A fiber-optic-based humidity sensor has been fabricated using Polarization Maintaining (PM) fiber coated with Chitosan, a moisture-sensitive polymer [1]. The sensing concept exploits the inherent characteristics of the PM fiber and is examined based on different humidity level which induces changes...
