NASC Colloquium: Optical Alignment of Large Telescopes

Laura Coyle '09, Optical Engingeer, Ball Aerospace & Technologies Corp and 2018 Optical Society of America Ambassador, will speak. This seminar will describe techniques for the optical alignment of large telescope systems. Based on the telescope’s optical design, alignment tolerances, and test constraints, a wide variety of approaches exist – including direct measurement of the surfaces through wavefront testing and indirect measurement using auxiliary optical systems. The alignment concept, advantages, and limitations of various approaches will be presented, as well as their practical application to specific telescope systems. Examples include: the alignment of the Wide Field Corrector for the 10-m Hobby Eberly Telescope, the interferometric test of the 24.5-m Giant Magellan Telescope primary mirror segments, and the ground verification and on orbit alignment plan for the 6.5-m James Webb Space Telescope. In addition to optical alignment, an overview of the benefits of student membership in the Optical Society of America will be presented. (Image copyright of NASA/Chris Gunn)
