Abstract
The IPOL mode of FORS on UT1 allows to measure high quality polarimetric images on a wide field of view. We have used this instrument during ESO observation period 65 to determine the respective orientation of circumstellar disks in pre Main Sequence (PMS) binaries. In this paper, we present our method and first results obtained with FORS/IPOL. Thanks to the top quality assistance of the VLT and FORS teams, our run has been remarkably successful and the instrument appears extremely well adapted to fine polarimetric measurements on a large field of view. This large field of view is essential to disentangle between intrinsic polarisation and interstellar polarisation. Our first results suggest that circumstellar disks tend to be aligned in PMS binaries.
