By using the Fourier Transform Infra-Red spectrometer (FTIR), spectral data of typical silicate minerals and river deposits were obtained. For a solid sample, a bi-directional reflectance spectrum and a hemispherical reflectance spectrum are similar, and a reflectance spectrum and an emittance spectrum indicate reverse correlation. We also examined the optimum conditions for spectral measurements, e.g., sample grain size, mixture ratio, etc. In reflectance spectra of river deposits, absorption features due to Si-O and Si-OH stretching vibrations in quartz and clay minerals were clearly observed in the samples collected in the sedimentaiy rock areas.By installing the step-scan option for the FTIR, we developed the instrument which enables to measure the absorption and emission spectra of chemically unstable species as the candidates of interstellar matter, and qualified the status of the experimental system. In order to simulate the disequilibrium condensation and/or evaporation process … More es occurred in the proto-planetary nebulae, the microwave nebulizer was combined with the FTIR spectrometer. As a result, we demonstrated that the experimental system developed in the present study is applicable to the in-situ spectroscopic measurement of the chemically reactive regions with high sensitivity and high wavelength resolution.We investigated remote sensing data analysis methodologies. Firstly, we developed a method to convert observation data to surface reflectance by using a snow field, and showed a relationship between laboratory spectra and remote sensing data. Spectral indices for discrimination of typical minerals and an algorithm to estimate silica contents from thermal infrared spectra were also proposed. Multispectral image data of moon surface obtained by Clementine were analyzed , and an algorithm was developed in order to estimate Ti and Fe contents by removing the space weathering effect. As a result, we obtained new findings on geology and evolution of Serenitatis area from the Clementine data. Less

利用傅里叶变换红外光谱仪（FTIR），获得了典型硅酸盐矿物和河流沉积物的光谱数据。对于固体样品，双向反射光谱与半球面反射光谱相似，反射光谱与发射光谱呈负相关关系。我们还考察了光谱测量的最佳条件，如样品粒度、混合比等。在河流沉积物的反射光谱中，在沉积岩区采集的样品中，清晰地观察到石英和粘土矿物中Si-O和Si-OH拉伸振动的吸收特征。通过安装FTIR的步进扫描选项，我们开发了能够测量化学不稳定物质作为星际物质候选者的吸收和发射光谱的仪器，并验证了实验系统的状态。为了模拟原行星状星云的不平衡冷凝和/或蒸发过程，将微波雾化器与FTIR光谱仪结合使用。结果表明，本研究开发的实验系统适用于化学反应区的原位光谱测量，具有高灵敏度和高波长分辨率。研究了遥感数据分析方法。首先，我们开发了一种利用雪地将观测数据转换为地表反射率的方法，并展示了实验室光谱与遥感数据之间的关系。提出了一种用于典型矿物鉴别的光谱指标，以及一种利用热红外光谱估算二氧化硅含量的算法。对Clementine获取的月球表面多光谱图像数据进行了分析，提出了一种去除空间风化效应估算月球表面Ti和Fe含量的算法。结果，我们从Clementine资料中获得了Serenitatis地区地质和演化的新发现。少
