Fiber Optic Sensors based on the effect of surface plasmon resonance using transparent conductive metal oxides

摘要

The invention relates to a sensor fiber optic device based on surface plasmon resonance (SPR) on transparent conducting metal oxide. More particularly, it relates to a system based on SPR with a layer of transparent conductive metal oxide sensor, which combines the advantages of eliminating the optical prism configuration Kretschmann towards a design optical fiber, portable, small and with the possibility of remote measurements and multiplexing. The incorporation of transparent conducting metal oxide involves the transfer to the infrared region of the wavelength of surface plasmons.
