Abstract

FIRSTv2 (Fibered Imager foR a Single Telescope version 2) is the upgrade of a post-AO spectro-interferometer (FIRST) that enables high contrast imaging and spectroscopy at spatial scales below the diffraction limit of a single telescope. It aims at using a photonic chip beam combiner, allowing the measurement of the complex visibility for every baseline independently thus improving the dynamic range. I will report on the first on-sky results obtained with several prototype chips integrated at the Subaru Telescope on unresolved and binary stars, for the first time in the visible.
