The Precision Integrated-Optics Near-infrared Imaging ExpeRiment (PIONIER) is an instrument for the VLTI astronomical observatory. It combines the light from four telescopes simultaneously and provide the equivalent angular resolution of a 100 m telescope. PIONIER has been built at LAOG and has been installed at VLTI in November 2010. After few nights of commissioning, it is now routinely delivering science data. == External links == * IPAG (Grenoble) - PIONIER project home * OSUG Grenoble – PIONIER instrument * ESO PIONIER – instrument description * ESO VLTI – about the interferometer at the VLT 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「PIONIER (VLTI)」の詳細全文を読む スポンサード リンク
