2013年12月24-26日，美国佛罗里达大学天文系教授葛健博士应邀访问长春光机所，中科院国家天文台副台长薛随建研究员和清华大学精密仪器系相关老师陪同访问。宣明所长对上述人员的来访表示热烈欢迎，并就科学研究与工程技术支持、美国三十米望远镜计划（TMT）两个方面与之进行了深入研讨。 

　　访问期间，葛健博士做了题目为《Advanced Instruments and Technologies for Detecting and Characterizing Exoplanets》的学术报告。报告深入浅出，分别从科学探索的需求、技术指标的要求、方案设计、工程实现、实验验证和数据分析六个主要方面阐述了从科学到研究的全过程。来访人员还参观了国家光栅制造与应用工程技术研究中心、中国科学院光学系统先进制造技术重点实验室。 

　　葛健博士简历：Dr. Jian Ge is a professor of astronomy at University of Florida. He was a University of Florida Research Foundation Professor in 2010-2013. He was an assistant professor at Department of Astronomy and Astrophysics of Penn State University in 2000-2004 before he joined UF as a tenured professor in 2004. He obtained his Ph.D in Astronomy at the University of Arizona in 1998 and his BS in theoretical physics at University of Science and Technology of China in 1989. He is the Principal Investigator of the MARVELS survey of the SDSS-III program in 2008-2014. He is the PI for the EXPERT, LiJET and EXPERT-III optical Doppler instruments and also FIRST near IR Doppler instrument. He led the development of the first silicon grisms, large format silicon immersion gratings and the Sine interferometric calibration source. He also led the development of the advanced image slicer integral field optics, and new generation coronagraphic image and pupil masks for TPF. His team discovered two new planets, sixteen brown dwarfs and hundreds of new binaries, and confirmed two transit planets. His team also discovered over 400 high redshift quasar 2175 Å dust absorbers, planetesimal infall around a young star, a protoplanetary disk, and molecular hydrogen in four high-redshift damped Lyman alpha quasar absorbers, and measured high redshift Cosmic Microwave Background Radiation temperatures.
