Paper Abstract

The fiber-optic refractometer made by the prism-taped fibers is presented. The prism tips of fibers had been making by polishing method and the endface of the load-in fiber was coating by the reflective thin film. The size of the fiber sensor head is of 250-260 microns. The fiber-optic sensor using visible laser diodes of 650-670 nm was performance for the directly distinguish of sugar content in the sugarcanes with accuracy range of 5.10-4. These refractometers are already to use for the sugarcane plantations.
