摘要：

We analyze the suitability of digital equipment with CCD arrays for polarization Measurements of solar coronal emission during eclipses. The effect of errors in the method on the derived plane of polarization is estimated. In principle, precise measurements of the plane of polarization can be used to determine the amplitude and direction of the Current of a heliospheric plasma sheet. The errors in ordinary nondigital photometric measurements (5%) are too large to enable the resolution of a number of problems having to do with the three-dimensional structure of the solar corona.
