Abstract
Sensors deployed for ocean observation are highly corroded by seawater. This study deals with the analysis of corrosion-resistant metal coated Fiber Bragg Grating (FBG) sensors for ocean temperature sensing. Firstly, the effect of thermally induced strain on FBG sensors coated with corrosion-resistant metal/alloy was computationally analyzed using Hookes law that reveals thermal strain sensitivity ranging from 28.6 μϵ/°C to 38.3 μϵ/°C for Stainless Steel 316L, Nickel and Nickel–Chromium alloy. This was followed by determining temperature sensing coefficient of FBG sensors coated with above mentioned metals/alloys that showed sensitivity ranging from 56.3 pm/°C to 75.3 pm/°C for two types of photosensitive fibers such as Germanium doped and Boron co-doped silica fibers for ocean temperature varying from 20 °C to 30 °C.
