Abstract

We present on-sky results obtained with the visible light prototype of the Fibered Imager foR Single Telescope (FIRST) mounted on the 3-m Shane Telescope at Lick Observatory and using its Adaptive Optics system. This instrument is dedicated to high angular resolution and high dynamic range imaging. Its principle combines both techniques of single-mode fiber interferometry and pupil remapping. Simulations predict a dynamic range up to 10⁶ at /D, or at a few tens of milliarcseconds at 630nm using an 8-m telescope. Laboratory experiments based on a 9-fiber prototype working in the 600nm–900nm spectral band successfully demonstrated the power of the concept. The same prototype has been set-up on the 3-m Shane telescope in July 2010. In this paper, we present the on-sky results obtained in October 2011 with an improved version of the instrument using 18 fibers. They clearly show the detection of the binary star Capella at the diffraction limit of the telescope.λ
