A Method for Improving the Spacial Resolution of the Observation of Magnetic Fields in the Solar Active Region

Abstract
Yunnan Observatory has obtained many valuable data of magnetic fields of solar active regions.However,only the average total magnitic fields intensity on an area of 2.3"×1.5" could be measured because of.the limitation of the polarization grating.In this paper a.new design is suggested by adding a Wallaston prism in the optical path without changing,the original instrument.The method could quite enhance the spatial resolution of the observation of magnetic fields in solar active regions.
