Abstract:
1. A surface plasmon sensor comprising: a light guide reflection plate comprising: a surface plasmon resonance layer, comprising a metal layer, formed on the first surface of the light guide reflection plate; a light emitting unit comprising a light source disposed on an end surface of the light guide reflection plate; and a light receiving element disposed on a second surface of the light guide reflection plate opposite the first surface, wherein the light guide reflection plate is configured to transmit light emitted by the light source, wherein the plurality of first reflection surfaces are configured to reflect the light to the surface plasmon resonance layer, wherein the metal layer is configured to reflect the light reflected by the plurality of first reflection surfaces, wherein the light guide reflection plate is configured to transmit the light reflected by the metal layer and emit the light out of the second surface to the light receiving element, and wherein the light receiving element is configured to receive the light reflected by the metal layer.
