| Abstract: | A novel fiber optic evanescent field absorption sensor having high sensitivity and linear dynamic range is proposed. High
sensitivity is achieved by using a U-shaped probe while linear response is obtained by preventing surface reactivity of the
silica core of the fiber with the solute molecules of the absorbing fluid. To prevent it, a thin film of a suitable polymer is developed on the bare core U-shaped probe. A good degree of reproducibility of the results is obtained. |
