| 摘 要： | 利用法布里珀罗振荡模构造了一种新型的光化学传感器。与传统的以表面等离子模和光导模为探针的迅衰场传感器不同 ,这种新型结构中被传感介质处于法布里珀罗腔的振荡场中 ,其能量在全部入射光能中的比重占得很大 ,使得这种传感器具有很高的灵敏度。实验证实这类传感器对葡萄糖溶液浓度和折射率的测量精度皆可达 10 - 5数量级以上

| Abstract: | A novel prism coupled device as an Fabry-Perot oscillating field sensor has been developed. In the proposed configuration, liquid or gaseous sample to be probed supports oscillating field in Fabry-Perot cavity, rather than evanescent field as in the conventional SPR sensors or the waveguide mode sensors. Because most energy of incident light is coupled in oscillating field, the sensor′s detection sensitivity is very high. Prototype sensor based on this approach has been successfully fabricated and tested. The detection limity for glucose solution is 10 -5 (mass fraction) in the experiments with the system. |
