Changes in Brightness of Lunar Details Dependent on the Azimuth and in Profiles of Lunar Indicatrices

摘要

The dependency of the brightness of lunar objects on different azimuths of the incident and reflected rays is studied. The effect of the different azimuths is shown. The cited sectional indicatrices are for i = 30 degrees, i = 60 degree planes, passing through the incident ray and perpendicular to the plane of incidence. The conclusions drawn are that these studies further confirm the condition of similarity of microreliefs of the lunar surface, and that the changes in brightness of the lunar seas and continents are dependent on azimuth changes and comparable to the data for crushed tuff, the size of which ranges from 2-6 mm.
