| titleOfInvention | Dual-channel liquid refractive index sensing system based on super surface |
| abstract | A dual channel, super-surface based liquid refractive index sensing system, comprising: the device comprises a super-surface sensing chip, a single-wavelength laser and two polarization detectors; the super-surface sensing chip comprises a transparent substrate and a two-dimensional metal nano antenna array; the two-dimensional metal nano antenna array is used for being in contact with a detected liquid medium to form a super surface when laser is vertically incident; the single-wavelength laser is used for vertically emitting single-wavelength light waves and forming resonance with the two-dimensional metal nano antenna array on the super surface; the two-dimensional metal nano antenna array comprises a first metal nano antenna array and a second metal nano antenna array, and polarization differentiation responses of different diffraction orders are realized after the two-dimensional metal nano antenna array resonates with a single wavelength light wave; and the two polarization detectors are arranged on the other side of the transmission surface of the transparent substrate and are used for detecting polarization dissimilarity responses of different diffraction orders. The invention has the advantages of small volume, easy integration, low cost, high sensitivity, high signal-to-noise ratio and strong anti-interference capability. |
