Observations show that Earth's climate has been warming. To study climate change, many ground-based and space-based instruments have been developed to observe Earth's land, air, water and ice. An imaging Fabry-Perot spectrometer (FPS) has been developed at York University to obtain accurate, detailed, and collocated measurements of atmosphere and to retrieve simultaneously surface pressure, aerosol information, and surface albedo from the measurements. One key subsystem of this spectrometer is a Fabry-Perot, which is driven by three piezoelectric actuators to achieve nanometer positioning. This instrument has been validated through two successful stratospheric balloon missions in September 2016 and April 2017. In this talk, the development of this instrument and some lessons learned from this mission will be presented.
Prof. Jinjun Shan joined York University as an Assistant Professor of Space Engineering in July 2006. He was promoted to Associate Professor in July 2011, and Full Professor in July 2016. He currently serves as the Undergraduate Program Director for Space Science and Engineering Program at York University. Prior to his appointment at York University, he was a Post-Doctoral Fellow at University of Toronto Institute for Aerospace Studies from Nov. 2003 to June 2016. He received his Ph.D. degree from Harbin Institute of Technology, China in 2002. Dr. Shan was awarded the Alexander von Humboldt (AvH) Fellowship, JSPS Invitation Fellowship, as well as Excellence in Teaching Award from York University. His current research interests are dynamics, control and navigation, smart materials and structures, and space instrumentation. He is the founding director of Spacecraft Dynamics Control and Navigation Laboratory (SDCNLab) at York University. Dr. Shan is also an Associate Editor for IEEE/ASME Transactions on Mechatronics and Journal of Franklin Institute.
