Paper Abstract

Imaging polarimetry offers a way to increase the contrast of light scattered from circumstellar material, enabling direct observation of exoplanets –possibly rocky– with the E-ELT. To actually characterize these planets, some spectral resolution is essential. With sufficient resolution –both spectral and spatial– the spectral differential imaging technique can be used in addition to the polarimetry to detect circumstellar point sources. We present the concept for a spectro-polarimetric integral field spectrograph for the EPICS-EPOL instrument and our current efforts to demonstrate this concept with our existing imaging polarimeter ExPo.
