Surface plasmon resonance sensor using rotating mirror |
摘要 |
Disclosed is a surface plasmon resonance sensor having a rotating mirror, including (a) an incident light source unit for oscillating a laser as incident light; (b) a polarizer for polarizing the incident light; (c) a rotating mirror having cylindrical or planar shapes for reflecting the polarized incident light to radiate disk-shaped light; (d) a light shielding film for allowing part of the disk-shaped light to pass therethrough and located adjacent to the central axis of the rotating mirror; (e) a cylinder lens for focusing the light passed through the light shielding film thereon; (f) a metal thin film for receiving the light focused on the cylinder lens to generate surface plasmon resonance; (g) a dielectric medium provided under the metal thin film; and (h) a detector for detecting the light reflected from the metal thin film. This surface plasmon resonance sensor can solve conventional interference problems of a laser being used as a light source to obtain an image for measurement of angle and two-dimensional reflected light intensity, including the deterioration of the quality of the image and the variation in the intensity of light source depending on the position of incidence.
