SURFACE PLASMON SENSOR AND REFRACTIVE INDEX MEASUREMENT METHOD |
摘要 |
<p>To provide a surface plasmon sensor for measuring a refractive index by which a refractive index can be easily measured with high accuracy without relying on an absorption curve. The surface plasmon sensor includes: a reflection plate which includes a metal layer having a periodic structure and on which a specimen is arranged; a light source which irradiates an incident light to the reflection plate; a light receiving part which receives a reflected light reflected on the reflection plate; and a measurement part which measures a refractive index of the specimen based on phase information on two kinds of waves which are included in reflected light reflected on a periodic structure surface and differ in polarization direction.</p> |
