【摘要】

Significant optical engineering advances at the University of Arizona are being made for design, fabrication, and construction of next generation astronomical telescopes. This summary review paper focuses on the technological advances in three key areas. First is the optical fabrication technique used for constructing next-generation telescope mirrors. Advances in ground-based telescopecontrol and instrumentation comprise the second area of development.   This includes active alignment of the laser truss based Large Binocular Telescope (LBT) prime focus camera, the new MOBIUS modular cross dispersion spectroscopy unit used at the prime focal plane of the LBT, and topological pupil segment optimization. Lastly, future space telescope concepts and enabling technologies are discussed. Among these, the Nautilus space observatory requires challenging alignment of segmented multi-order diffractive elements. The OASIS terahertz space telescope presents unique challenges for characterizing the inflatable primary mirror, and the Hyperion space telescope pushes the limits of high spectral resolution, farUV spectroscopy. The Coronagraphic Debris and Exoplanet Exploring Pioneer (CDEEP) is a Small Satellite (SmallSat) mission concept for high-contrast imaging of circumstellar disks and exoplanets using vector vortex coronagraph. These advances in optical  engineering technologies will help mankind to probe, explore, and understand the scientific beauty of our universe.

Daewook Kim is an associate professor of optical sciences and astronomy at the University of Arizona. He has been working in the optical engineering field for more than 15 years, including NASA Aspera UV space telescope mission, 25 m diameter Giant Magellan Telescope, and commercial Augmented Reality freeform glass project. His main research area covers precision freeform optics design, fabrication, and various metrology topics, such as interferometric test systems using computer-generated hologram, wavefront curvature measurement, and dynamic deflectometry system. For the past 10 years, Daewook has been chairing conference programs including the Optical Manufacturing and Testing conference (SPIE), Optical Fabrication and Testing conference (OPTICA), and the Astronomical Optics: Design, Manufacture, and Test of Space and Ground Systems conference (SPIE). He is also teaching the SPIE Optical Testing Short Courses. He has published more than 200 journal/conference papers and served as an associate editor for the Optics Express journal for 7 years. He gave more than 20 plenary, keynote, colloquium talks at various international conferences and universities. Prof. Kim is an SPIE Fellow.
