摘要： A differential detection technique combined with a surface plasmon resonance technique is proposed for refractive index variation measurement. The experimental results demonstrate that our system can attain a resolution of 1.2 × 10 −5 RIU (refractive index unit). In addition, a method for two-dimensional detection of the refractive index variation is demonstrated. The system is free from the influence of optical source fluctuation, and can improve the measurement sensitivity. 其他題名： OPT REV 出版者： Japan: Optical Society of Japan 出版日期： 2013-03-01 出處： Optical review, 2013-03, Vol.20 (2), p.182-184 版權： The Optical Society of Japan 2013 識別號： ISSN: 1340-6000 識別號： EISSN: 1349-9432 識別號： DOI: 10.1007/s10043-013-0030-5
