    Abstract:

    Hapke model has been widely used in the photometric study of regolith as the parameters has specific photometric and physical meaning. To reverse these parameters, photometric observations are needed for a wide range of incidence, emission, and phase angles of the regolith. However, it is difficult to have such wide range angles in the remote sensing and in situ observation. So, it is very important to know how we can get precise result with the limited observations and we can do the research at laboratory. In this work, we got the reflectance of olivine with large range of phase angle by ASD spectrometer and got reflectance of two kinds of Lunar analog samples by Chang’E-3 VIS-NIR Imaging Spectrometer. Also we learned how to reverse Hapke model parameters. As a result, we find that we can get accurate result with limited measurements. Also, we have got some result of two Lunar analog samples (one with glass and the other without glass) with analysis of relative parameters of Hapke model.
