近红外中信噪比的定义从大体上讲很明确,但是具体到究竟怎么计算,我还是觉得有点糊涂。 有篇文献里是这么说的: Let's first define the spectral SNR as the root-mean-square(rms)value of the inverse of the 100% line: SNR=(1/100%line)rms ---(注:rms是下角标)---Eq(1) 后面一段又说了: Following the definition in Eq.(1),we obtain the SNR values by taking the rms values of the inverse of the 100% lines. In this case, we produced the 100% lines by taking the ratio of numerous transsmission spectra of water through a 2-mm path-length quartz cuvette. 那么这个100%line 是什么意思,是他们自己定义的还是大多数人都约定了的? 希望大家指教一下
