我们提出了一种表面敏感光学传感器，其基于通过这样的相位检测方法对表面等离子体的相位进行配准，该相位检测方法使得可以基本上消除对由于温度、组成和其它变化而引起的液体的折射率变化的不期望的敏感性。这一目标已经通过检测表面等离子体波和体波之间的干扰，在掠射角传播的表面上。所提出的干涉测量方法也不会受到振动噪声的影响。(C)2003 Elsevier B.V.保留所有权利。
We present a surface sensitive optical sensor based on registration of the phase of surface plasmons by such a method of the phase detection that makes it possible to essentially eliminate an undesirable sensitivity to variations of refraction index of a liquid due to temperature, composition and other changes. This objective has been achieved by detecting the interference between the surface plasmon wave and a bulk wave propagating at grazing angle just above the surface. The proposed interferometric method also does not suffer from vibrational noise. (C) 2003 Elsevier B.V. All rights reserved.
