以找矿为目的的航空红外细分光谱地质遥感技术,近年来取得了较大进展。各种蚀变岩在2.0~2.5微米敏感范围内,有明显的光谱吸收特征,其反射光谱曲线具有与蚀变类型和蚀变强度相对应的形状与大小。非蚀变和弱蚀变岩石的光谱则表现比较平滑,反射率也较低。应用上海技术物理所研制的航空红外细分光谱扫描仪,可以获取这种红外窄波段多光谱信息,通过处理和分析,直接应用于地质找矿。该仪器六个工作波段的中心波长为2.035微米,2.087微米,2.143微米,2.200微米,2.280微米,2.380微米,带宽0.1微米,现已投入实用性遥感飞行。1986~1987年在新疆阿勒泰地区和西准噶尔地区飞行的几个已知矿区(带)上,获得了丰富的地质遥感信息,全部数据采用TEAC
In order to prospecting for the purpose of aviation infrared spectral spectral geology remote sensing technology, made great progress in recent years. Various alteration rocks have obvious spectral absorption characteristics in the sensitive range of 2.0-2.5 μm, and their reflection spectral curves have shapes and sizes corresponding to the types of alteration and the intensity of alteration. The spectra of non-altered and weakly altered rocks show a smoother and lower reflectance. Application of the Shanghai Institute of Technical Physics developed infrared spectral sub-spectral scanners, you can get this infrared narrow-band multi-spectral information, through processing and analysis, directly applied to geological prospecting. The center wavelengths of the six working bands of the instrument are 2.035 μm, 2.087 μm, 2.143 μm, 2.200 μm, 2.280 μm, 2.380 μm, and 0.1 μm bandwidth, and are now being put into practical remote sensing flight. From 1986 to 1987, we obtained abundant geological remote sensing information on several known mining areas (belts) flying in the Altay region and the West Junggar region in Xinjiang. All the data were obtained using TEAC
