In this project, we propose to monitor dental resin curing dynamics in real time using a highly accurate surface plasmon resonance (SPR) based optical sensor technique. We will explore both linear SPR sensing modality, where the position of an intensity dip of a reflected light wave is monitored under the SPR condition and a nonlinear SPR sensing modality. The nonlinear SPR sensor operation principle is based on recently discovered by the PI spectral switches of sum-frequency reflected wave near the SPR condition when the resin is illuminated with broadband polychromatic light. We expect the novel technique to furnish our industrial partner, BlueLight Analytics with a highly accurate tool to determine the proper curing time for a wide set of dental resins and light curing units.

在这个项目中，我们建议使用基于高度精确的表面等离子体共振（SPR）的光学传感器技术实时监视牙齿树脂固化动力学。我们将探索两种线性SPR感应方式，其中在SPR条件下监测反射光波的强度倾角的位置和非线性SPR感应方式。非线性SPR传感器操作原理是基于最近通过宽带多色光照明树脂在SPR条件附近的SUM频谱反射波的PI光谱开关。我们希望这种新颖的技术能够为我们的工业合作伙伴，Bluelight Analytics提供高度准确的工具，以确定一套广泛的牙科树脂和轻质固化单元的适当固化时间。
