Abstract: 

Using the 50-cm telescope of the Maidanak (Middle Asia) observatory, polarimetric observations of the Moon at leff = 0.48 and 0.63 mm were carried out. The Canon-350D camera equipped with the CMOS array and the rotated film polaroid were used for imaging. A part of the lunar disk which comprises the north part of Ocean Procellarum was studied. Albedo, polarization degree, color-index, and polarimetric color ratio at a phase angle of 96° were imaged for the area. The last-named parameter was imaged with a resolution of about 1 êm for the first time. The image obtained for this parameter resembles the color-index distribution, though important differences can be seen. This shows that spectropolarimetric observations of the Moon can give new information on the composition and structure of the lunar surface.
