Abstract

We present an analysis of systematic errors in an apparatus for measuring linear polarization in far-infrared observations of astrophysical objects. In particular, we examine a systematic effect which has until now limited the accuracy of measurement of spatially extended sources. We describe modifications to the apparatus which have reduced the effect to almost negligible levels.
