为了简化用于确定表面等离子体共振（SPR）角度的算法以用于特殊应用和发展趋势，已经提出了用于确定SPR角度的快速方法，称为固定边界质心算法。通过两个实验从运算时间、散粒噪声敏感度、信噪比、分辨率和测量范围等方面对三种质心算法进行了比较。虽然该方法的测量范围较窄，但其他性能指标均优于其他两种质心法。该方法具有速度快、一致性好、误差小、信噪比高、分辨率高等优点。因此，它有可能被广泛采用。
To simplify the algorithm for determining the surface plasmon resonance (SPR) angle for special applications and development trends, a fast method for determining an SPR angle, called the fixed-boundary centroid algorithm, has been proposed. Two experiments were conducted to compare three centroid algorithms from the aspects of the operation time, sensitivity to shot noise, signal-to-noise ratio (SNR), resolution, and measurement range. Although the measurement range of this method was narrower, the other performance indices were all better than the other two centroid methods. This method has outstanding performance, high speed, good conformity, low error and a high SNR and resolution. It thus has the potential to be widely adopted.
