我们提出了一种新的高对比度成像仪的京都4米分段望远镜称为SEICA（第二代系外行星成像仪与日冕自适应光学），旨在检测和表征附近恒星周围10 AU内的自发光气体巨星。SEICA是积极优化的高性能在非常小的内部工作角，10- 6检测对比度在0”.1在1小时的积分。我们将于2016年开始天空调试测试，并于2017年开始科学观测。由于这是首次在分段望远镜上实现高对比度成像，因此SEICA是在极大望远镜上实现未来高对比度科学的重要一步。本文介绍了SEICA计划的总体情况和在给定大气条件下的最终性能的概念设计。
We propose a new high contrast imager for Kyoto 4m segmented telescope called SEICA (Second-generation Exoplanet Imager with Coronagraphic Adaptive optics), aiming at detection and characterization of selfluminous gas giants within 10AU around nearby stars. SEICA is aggressively optimized for high performance at very small inner working angle, 10-6detection contrast at 0".1 in 1-hour integration. We start the on-sky commissioning test in 2016 and the science observations in 2017. Since it is the first time to realize the highcontrast imaging on the segmented telescope, SEICA is an important step toward future high contrast sciences on Extremely Large Telescopes (ELTs). This paper presents an overall of the SEICA program and the conceptual design for ultimate performance under given atmospheric conditions.
