The design and analysis of a noble surface plasmon resonance based pressure sensor
The optical fiber sensor for higher pressure detection based on surface plasmon resonance (SPR) phenomena is design and analysed. The optical fiber is coated with a thin film of metal by removing cladding from core of a multi mode optical fiber. The calculated pressure sensitivity is based on two parameter. First one is the derivative of the resonance wavelength of SPR based optical sensor with respect to the refractive index of surrounding medium; the second is the derivative of refractive index of polymer with respect to the pressure. The proposed structure can be suitable for high sensitivity pressure measurements, for various industrial applications.
