摘要：

We present 43 GHz VLBA polarization observations of the quasar 3C 454.3 and discuss technical aspects concerning the calibration of millimeter VLBI polarimetry. Significant polarization fine structure is observed near the core of 3C 454.3, with a predominant electric field vector orientation parallel to the projected jet direction. This contrasts with previous centimeter VLBI polarimetry of quasars for which an orthogonal polarization orientation is generally found on larger VLBI scales.
