本文分析了聚焦表面等离子体激元的空间频率响应与样品双折射之间的关系。样品由光寻址偶氮苯官能化均聚物的薄膜组成。由于偶氮聚合物的顺反弛豫态的光致异构化，在样品中诱导各向异性，并且在出射光瞳平面处观察到椭圆率为1.082的吸收图案。对吸收图样的椭圆率和取向的定量分析揭示了样品的双折射大小和快轴方向。模拟和实验结果。
In this paper we analyze the relationship between the spatial frequency response of focused surface plasmon with the birefringence of the sample. The sample consists of thin film of photo-addressable azobenzene functionalized homopolymer. Due to the photoisomerization of the cis-trans relaxation states of azopolymer, anisotropy is induced in the sample and absorption pattern with ellipticity of 1.082 is observed at the exit pupil plane. Quantitative analysis of the ellipticity and orientation of the absorption pattern reveals the magnitude of birefringence and direction of fast axis of the sample. Simulated and experimental results are presented.
