Abstract:
Currently several development activities for the European Solar Telescope (EST) are ongoing, one of these is Getting Ready for EST (GREST), a venture for the development of new sensor and detector technologies for EST. Among other objectives, EST will perform time resolved, high precision polarimetric imaging. These measurements require detector systems that are capable of detecting even smallest changes in the polarization of light. At the MPG-HLL we developed a sensor concept for such a system, the Quadropix DEPFET. These devices offer in-situ storage of up to four independent images without reducing the sensors fill-factor. For polarimetric applications this properties can be used for polarimetry measurements at high modulation frequencies.
