很快，大型望远镜（VLT的SPHERE，Gemini的GPI）的专用仪器开发将通过直接成像和光谱学大量发现和探索自发光巨行星。下一代30米至40米的地面望远镜，即极大望远镜（ELT），有可能极大地扩大发现空间，使其能够在反射光中看到更古老的巨行星，最终甚至是少量的岩石行星。EPICS是欧洲ELT的建议仪器，致力于通过直接成像和光谱法检测和表征expolanets。EPICS目前正在进行一项由一个大型欧洲财团进行的A阶段研究，该研究将通过模拟和演示实验研究最先进的衍射和散斑抑制技术，以提供最高的对比度。2010年初研究的最终结果将是该仪器的概念设计和开发计划。我们将介绍EPICS概念，包括性能分析和原型实验的初步结果，并讨论EPICS的主要挑战和科学能力。
Very soon, dedicated instruments developments at large telescopes (SPHERE for the VLT, GPI for Gemini) are about to discover and explore self-luminous giant planets by direct imaging and spectroscopy in significant numbers. The next generation of 30m-40m ground-based telescopes, the Extremely Large Telescopes (ELTs), have the potential to dramatically enlarge the discovery space towards older giant planets seen in reflected light and ultimately even a small number of rocky planets. EPICS is a proposed instrument for the European ELT, dedicated to the detection and characterization of expolanets by direct imaging and spectroscopy. EPICS is currently mid-way through a phase-A study carried out by a large European consortium which - by simulations and demonstration experiments - will investigate state-of-the-art diffraction and speckle suppression techniques to deliver highest contrasts. The final result of the study early 2010 will be a conceptual design and a development plan for the instrument. We will present the EPICS concept including the performance analysis and first results from prototyping experiments and discuss the main challenges and science capabilities of EPICS.
