提出了一种差分表面等离子体椭圆偏振技术，该技术允许在优于5 × 10（-7）折射率单位的水平上感测水溶液中的折射率变化。这种灵敏度水平与目前最好的基于表面等离子体的传感系统相当，并且可以被实现为生物化学传感器。该技术具有理想地适合于多通道阵列传感器的开发的额外优点。
A differential surface plasmon ellipsometry technique is presented which allows the sensing of refractive index changes in aqueous solutions at the level of better than 5 x 10(-7) refractive index units. This level of sensitivity is comparable to the best currently available surface plasmon based sensing systems and can be implemented as a bio-chemical sensor. The technique has the additional advantage of being ideally suited to the development of a multi-channel array sensor.
