Abstract

In this paper, a new parallel scan spectral surface plasmon resonance (SPR) 2D sensing system is presented. With a lineshaped light illumination, an image acquired with area CCD detector provides both SPR wavelength information and 1D spatial distribution. Thus, 2D distribution of refractive index of the entire sensing plane can be obtained with 1D optical line parallel scan. A refractive index distribution model and a manually dotted DNA array are measured with this system. The technology shows advantages of both high sensitivity and high throughput in these results, and could have potential applications in biochips analysis.
