The Fresnel-FRee Experiment for EPICS (FFREE) is a test bench developed in the frame of high contrast imaging for ELTs. Its purpose is to support the EPICS project (Exo-planets Imaging Camera and Spectrograph) for the European Extremely Large Telescope. FFREE is dedicated to the investigation of chromatic effects in the rejection of static speckles either with a deformable mirror (speckle nulling by Electric Field Conjugation, EFC) or by post-processing (spectral deconvolution). Emphasis is put on...
