Near-IR and visual high resolution polarimetric imaging with AO systems

Many spectacular polarimetric images have been obtained in recent years with adaptive optics (AO) instruments at large telescopes because they profit significantly from the high spatial resolution. This paper summarizes some basic principles for AO polarimetry, discusses challenges and limitations of these systems, and describes results which illustrate the performance of AO polarimeters for the investigation of circumstellar disks, of dusty winds from evolved stars, and for the search of reflecting extra-solar planets.
