The Study of Bidirectional Reflectance Feature of the Spinel Based on the Space Weathering

This paper briefly introduces the bidirectional reflectance feature of spinel based on space weathering. The distribution of the bidirectional reflectance feature of spinel under the different conditions of space weathering was simulated using the Hapke model. The results show that the absorption features at 0.6μm and 1.9μm could be used to determine the spinel when the Moon Mineralogy Mapper (M3) data is applied. However, when the Chang’e-1 Interference Imaging Spectrometer (IIM) data is used, the space weathering level should be first analyzed, and then the absorption features at 0.6μm and 0.9μm could be applied to identify the mineral. These results provide the basis of identifying spinel using absorptive positions and depths of the spinel, which can also be applied to M3 data and Chang’e-1 IIM data processing.
