中红外光谱在月球探测中的应用 总被引:1,自引:0,他引:1
硅酸盐矿物的中红外光谱一般具有明显的CF特征和Reststrahlen吸收带,这些特征都与硅酸盐的组成密切相关,可以作为判别其组成的指示特征。月球表面的主要矿物有辉石、斜长石、钛铁矿和橄榄石,其中除了钛铁矿以外,都属于硅酸盐的范畴。如果充分利用月球表面硅酸盐的红外光谱特征,即CF特征和Reststrahlen吸收带,将可以用于探测VIS-NIR光谱无法完成的探测目标:钙长石、橄榄石、石英和碱性长石等。如果在嫦娥工程的后续探测器(如轨道器、月球车或者软着陆平台)上搭载中红外光谱仪对月表物质进行探测,将有利于成功实现对月球表面的矿物和岩石的精确探测,这也将是我国首次采用中红外光谱探测仪对月球进行系统的矿物与岩石探测。 相似文献

Due to the rapid development of modern science and technology, many advanced sensors have been put into use to explore our solar system, including the Moon. With the help of those detectors,we can retrieve more information to about the Moon‘ s composition and evolution. The Clementine (January, 1994), Lunar Prospector (January, 1998) and especially Smart-1 ( September, 2003) launched successively have demonstrated the next-generation planet exploration techniques. Now China has decided to send a probe to the Moon. So it is necessary to overview the development of detectors used for the scientific observation of the Moon. In this paper, some main instruments used to acquire geochemistry information are described, which include UV-VIS-NIR CCD imaging spectroscope, neutronray, gamma-ray, and X-ray spectrometers. Moreover, the payloads of China‘ s first lunar satellite are introduced briefly. 相似文献
