Biography

Dae Wook Kim is Assistant Professor at the College of Optical Sciences, University of Arizona. He graduated in Physics and Astronomy, Yonsei University, South Korea in 2003. He earned his Master's and PhD degrees in the College of Optical Sciences, University of Arizona, USA in 2008 and 2009. He is currently a principal scientist for projects that develop and implement advanced technologies for building and testing large optical systems and astronomical telescope mirrors.


He has been working in the optical engineering field for more than 10 years, focusing on very large astronomical optics such as 25m in diameter Giant Magellan Telescope primary mirror and 4.2m Advanced Technology Solar Telescope primary mirror. His main research area has been over the precision optical fabrication field. He is also working on various optical metrology topics such as interferometric testing using computer generated holograms, direct curvature measurement and dynamic deflectometry systems.


He is teaching a graduate course "Optical Testing" and "Fundamentals of Applied Optics Laboratory" at the University of Arizona, and has been served as a co-lecturer for "Computer Generated Holography and Diffractive Optical Elements Workshop" co-sponsored by SPIE. He has been authored/co-authored more than 60 journal articles and conference proceedings including some cover-featured, invited or the most downloaded papers.
He is currently a chair/co-chair of the International Symposium on Optical Engineering + Applications, Optical Manufacturing and Testing (SPIE), the International Symposium on Optoelectronic Technology and Application, Telescopes and Large Optics (SPIE, OSA and Chinese Society of Astronautics), and the Topical Meeting on Optical Fabrication and Testing of the Optical Society of America (OSA). He is an Associate Editor for Optics Express journal.




 

Lecture Title(s)

Giant Opto-mechanical Time Machines enabled by Dynamic Optics Technology

Three giant imaging machines' eyes coupling diffraction-limited spatial resolution with unprecedented photon collection power, astronomical primary mirrors for the next generation telescopes, 25m Giant Magellan Telescope, 8.4m Large Synoptic Survey Telescope, and 4.2m Daniel K. Inouye Solar Telescope, have been created at the University of Arizona. Those precision optics were efficiently produced using a computer controlled optical surfacing (CCOS) process. Various new approaches advancing the current CCOS processes have been developed and implemented to manufacture highly aspheric or free-form optics at the Richard F. Caris Mirror Lab (RFCML), Optical Engineering and Fabrication Facility (OEFF) and the Large Optics Fabrication and Testing (LOFT) group at the University of Arizona. Various exciting technologies including actively controlled Stressed lap, Silly-Putty lap using non-Newtonian fluid, IR deflectometry using a hot wire, and precision dynamic freeform metrology using an iPhone are presented with some actual data demonstrating the exceptional performance of the precision optics manufacturing process. Finally, we can "time-travel" the Universe using the priceless mirrors.
