本文采用自行搭建的实验系统,研究了氯化铵溶液的光谱特性。实验基于多次测量取平均的光谱数据,采用光谱归一化的方法消除光强变化引起的测量误差,通过计算不同浓度的差谱,提取了对氯化铵浓度敏感的733nm、833nm特征波段。两波段的浓度回归结果表明,差谱强度与浓度具有良好的线性关系,对高光谱遥感探测的应用具有实际意义。

The spectral characteristics of the ammonium chloride solution was studied using the self-constructed experimental system. Based on the average spectrum data, the measuring error due to the changing intensity was eliminated using the method of spectral normalization, and the feature bands (733nm, 833nm) sensitive to ammoni-um chloride concentration was extracted by calculating the differential spectrum of the various concentration. The re-gressing concentration results of the two bands (733nm, 833nm) show, the relation between the differential spectrum intensity and the solution concentration is properly linear, which is practical to the application of hyper-spectral re-mote sensing detection.
