| 摘 要： | 针对一种新兴生物检测方法——表面等离子体波共振(SPR)技术,文中SPR传感系统采用偏振干涉和角度调制方案,使SPR传感灵敏度与光复反射系数的模和相位都相关,从而实现较大线形范围内的高灵敏测量。同时开展了该SPR传感系统在环保领域的应用研究,SPR共振信号可实时随甲烷含量线性改变,气体检测灵敏度达到1 070ppm,实验结果验证了这种SPR传感技术的检测性能并显示了其在环保监测领域的应用潜力。

| Abstract: | This paper focuses on a rising biomedical optical technique-Surface Plasmon Resonance(SPR).Our SPR sensor uses polarization interferometer and angle modulation techniques.Theoretical analysis shows that our sensing system can accomplish a high resolution measurement of refractive index in a wide linear range,and the sensitivity is correlated with the modulus and phase of the complex reflection coefficient.We also study the application of our SPR sensors in environmental monitoring.Experimental results show ... |
