我们研究了光与表面等离子体相互作用引起的光偏振的变化。在此基础上，提出了一种新的表面等离子体共振(SPR)传感器的偏振控制方案。给出了采用新的偏振控制方案的SPR传感器的理论模型。理论分析表明，所提出的偏振控制方案可以显著提高SPR传感器的灵敏度和工作范围。利用实验室SPR成像传感器系统对理论分析的结果进行了实验验证。
We study changes in the polarization of a light induced by the interaction of light with a surface plasmon. Based on the results of the study, a novel polarization control scheme for surface plasmon resonance (SPR) sensors is proposed. Theoretical model of an SPR sensor employing the new polarization control scheme is presented. The theoretical analysis suggests that the proposed polarization control scheme can significantly improve sensitivity and operating range of SPR sensors. Results of the theoretical analysis are validated experimentally using a laboratory SPR imaging sensor system with the proposed polarization control.
