| Research Abstract |
The interior of the Moon can be effectively investigated by observations of the lunar rotation using a small telescope set on the lunar surface. We developed a small telescope of PZT (Photographic Zenith Tube) type, assuming a future lunar mission which will set the telescope on the Moon. It was shown that a diffraction lens in the objective can loosen the temperature condition required for accurate observations very much. We developed a mercury pool which can reduce the effects of vibrations on the observational accuracy, considering the vibration of the mercury surface may cause a serious effect.
