我们描述了一种平行扫描光谱表面等离子体共振（SPR）成像技术。我们证明实验，与线形光照明，与面阵CCD探测器获得的图像提供SPR波长信息和一维空间分布。因此，整个传感平面的折射率的二维分布可以通过一维光学线平行扫描来获得。该技术具有高灵敏度和高通量的优点，在生物芯片分析中具有潜在的应用前景。(C)2008年美国光学学会
We describe a parallel scan spectral surface plasmon resonance (SPR) imaging technique. We demonstrate experimentally, with a line-shaped light illumination, that an image acquired with an area CCD detector provides both SPR wavelength information and one-dimensional spatial distribution. Thus two-dimensional distribution of the refractive index of the entire sensing plane can be obtained with a one-dimensional optical line parallel scan. The technique offers advantages of both high sensitivity and high throughput, and could have potential applications in biochips analysis. (C) 2008 Optical Society of America
