THE SPECTRAL-POLARIZATION CHARACTERISTICS OF THE LUNAR SURFACE,

Abstract

For the purpose of determining the dependency of the degree of polarization of lunar details on the wave length, a spectrographic survey of the lunar surface was performed near the quadratures by the author in June and July 1959 with a 220mm A3T-7 telescope, using three different positions of a polaroid mounted in front of the spectrograph's slit. Angular positions of the polaroid were: 0 deg, 60 deg and 120 deg. A total of 108 spectrograms of 12 lunar regions were taken, which included Plinius, Mare Tranquillitatis (3 regions), Palus Somni, Ray of Proclus, Oceanus Procellarum (3 regions), Copernicus, and ray aureoles of Copernicus and Kepler. Monochromatic values of polarization degree P sub lambda were calculated by V. G. Fesenkov's formula. An examination of the instrumental polarization, revealed an equality of 0.07 which was constant in the interval 390-620 millimicron. (Author)
