PHOTOGRAPHIC POLARIMETRY OF THE MOON WITH LIGHT FILTER,
Abstract
A study of polarization characteristics of the lunar features with regard to the wave length of light yielded the following results: (1) The majority of studied lunar details has maximum degrees of polarization in blue rays, which, on the basis of the results obtained by Umov, are in agreement with a positive value for the color index of the moon. (2) Certain lunar details have a maximum degree of polarization in red rays which may indicate the presence of a green or blue hue. (3) Considering only red and blue light filters, the degree of polarization on a large lunar region has a maximum in blue along Tycho's ray; after that, the curves run almost together. This agrees with a fact that the red shade is seen (as in the crater) up to a certain distance from the crater of a given ray. (4) A lunar polarimetric method with filters can produce interesting results, especially if we compare them with similar measurements of terrestrial substances. (5) The experiment of photographic polarimetry of the moon with light filters has shown that identical measurements with the help of electropolarimetry will be more precise and less laborious.
