| Abstract: | Liquid refractive index changes with its concentration and the change can be measured through its absorption spectrum, according to this theory, we present a Symmetrical metal - cladding optical waveguide sensing system, the characteristie curves of liquid with different concentration is obtained by using a symmetric metal cladding optical waveguide. the experimental results show that the sensing system features simple structure, low cost and high sensitivity. |
