这份报纸论述表面电浆子回声(SPR ) 成像系统基于尖调整(AM ) 和紧张测量(IM ) 一起避免扫描设备的角度的机械错误。SPR 反响的角度被尖扫描发现方法然后轻紧张变化在一个固定事件角度是镇定的。甘油坡度答案(0%,1%,2%,3%(重量百分比)甘油溶解在水里)实验被进行,它显示最好固定的角度地点是 SPR 吸收山峰和中央区域的线性范围的中间信号是比边阶区域的那些更一致的。SPR 图象的不同区域的敏感差别被学习,并且一个优化算法被开发。
This paper presents a surface plasmon resonance (SPR) imaging system based on angular modulation (AM) and intensity measurement (IM) together to avoid the mechanical errors of the angle scanning device. The SPR resonant angle was found by angular scanning method and then the light intensity changes were collected at a fixed incident angle. Glycerol gradient solution (0%, 1%, 2%, 3% (weight percentage) glycerol dissolved in water) experiments were conducted, which indicate that the best fixed angle location is the middle of the linear range of SPR absorption peak and the central area signals are more uniform than those of the border areas. The sensitivity differences of different areas of SPR images are studied, and an optimized algorithm is developed.
