2016年10月11日下午14:00，美国罗彻斯特大学光学研究所的Jannick P. Rolland教授应邀到bob手机在线登陆光电学院作题为“Freeform Optics in Imaging Instrumentation”的学术讲座。王涌天教授、杨健教授、宋勇教授、董立泉副研究员以及光电学院的研究生参加了此次讲座。讲座由杨健教授主持。

　　自由曲面光学元件是光电产品中的关键部件，是先进光学工程领域的前沿代表性技术之一。在讲座中，Rolland教授讲述了应用于照明及成像的自由曲面光学设计，以及自由曲面光学器件的发展情况。由于光学自由曲面的结构复杂性和多样性，给设计和精密制造这些自由曲面提出了许多研究挑战，Rolland教授特别强调了设计中的像差理论和像差评价方法。随后，给出了一些具体的设计案例，如三反消像差透镜、取景器及光谱仪等。自由曲面光学为照明和成像仪器开创了一个光明的未来。

　　讲座之后，Rolland教授与参会的学生们进行了亲切的交流，回答了大家提出的问题。Rolland教授的报告生动精彩，同学们反响热烈。

　　Jannick P. Rolland教授简介：

　　Jannick Rolland is the Brian J. Thompson Professor of Optical Engineering at the Institute of Optics at the University of Rochester and Director of the NSF I/UCRC Center for Freeform Optics (CeFO).  She also directs of the R.E. Hopkins Center for Optical Design and Engineering and the ODALab (www.odalab-spectrum.org) that synergize with CeFO. Passionate about translating inventions out of the research laboratory to benefit society, she co-founded LighTopTech Corp., a startup focused on advanced optical metrology, where she serves as Chief Technology Officer.  She earned an Optical Engineering Diploma from the Institut D'Optique Théorique et Appliquée in France and an MS and PhD in Optical Science from the University of Arizona. Professor Rolland is a Fellow of OSA, SPIE, and NYSTAR.  Professor Rolland served on the Editorial Board of Presence (MIT Press) (1996-2006) as well as Associate Editor of Optical Engineering (1999-2004) and IEEE publications (2007-2016). She was a Director at Large on the OSA Board of Directors (2010-2013) and currently serves as Topical Editor of Optics Letters. She is the recipient of the 2014 David Richardson Medal.
