HIGH RESOLUTION SURFACE PLASMON RESONANCE SENSOR WITH IMPROVE STABILITY AND A SENSOR SYSTEM USING THE SAME

摘要

PURPOSE: A high resolution surface plasmon resonance sensor and a sensor system using the same are provided to improve response to changes in external environment or local area by increasing the electric field intensity on the surface of metal film.;CONSTITUTION: A high resolution surface plasmon resonance sensor comprises a light transmission unit(10) and surface plasmon excitation units(12,14,16). As a signal beam(20) enters the light transmission unit, the light transmission unit forms an evanescent field. The surface plasmon excitation units excite surface plasmon with the evanescent field and induce surface plasmon resonance. A dielectric layer is inserted in the metal layers of the surface plasmon excitation units.;COPYRIGHT KIPO 2010
