Freeform Optics
10 June 2019 – 12 June 2019 OSA, Washington, District of Columbia United States
Freeform Optics explores the evolving impact of freeform optical surfaces on optical systems for both imaging and illumination. New fabrication techniques that create optical surfaces that are not surfaces of revolution open an expansive new space for optical systems. Particularly enabled systems include illumination systems, head-worn displays and mid- and long-wave pervasive surveillance systems. But optical testing methods for these new surfaces are lacking, and the theory and implementation of an aberration theory as a basis for optical design of these surfaces was only unraveled in 2012. The scope features work on the optical design of imaging systems with freeform surfaces, evolving methods for surface representation for illumination system optimization and a perspective on the new challenges these surface present to optical testing.

Building A Better World: A Real World Application of Optical Technology
Through DigitalGlobe’s maps and analytics, satellite imagery is used for an extensive set of applications. This paper shows how at Maxar Technologies, we use precision optics to fulfill our mission to “Build a Better World.”
Amy Newbury is a Director and Aerospace Fellow at DigitalGlobe, a Maxar Technologies company. She graduated with a PhD in Physics from Princeton University after which she was a National Research Council Post-Doctoral fellow at the National Institutes of Standards and Technology. Since then, she has worked in the aerospace field, first at MIT Lincoln Laboratory, then as a Staff Consultant at Ball Aerospace. She has been at DigitalGlobe for the past 8 years. While at Ball Aerospace, she served as Lead Engineer for several programs including a NOAA sounder instrument study and for the LANDSAT Operational Land Imager instrument. At DigitalGlobe, she worked extensively on the suite of imagers on the Worldview-3 satellite. She is currently the Chief Instrument Engineer for the Legion constellation slated to launch in the 2021 timeframe, and continuesto explore future satellite missions aligned with Maxar's purpose to “Build a better world”.

Folded Freeform Optics for Virtual Reality
Future virtual reality will require optics enabling much slimmer headsets, such as folded (catadioptric) architectures that will be reviewed here, from the classical pancake lens to the latest freeform multichannel Thineyes® solutions proposed by Limbak.
Pablo Benitez is professor at the Technical University of Madrid, Spain, where he leads the Optical Engineering group. In the last 20 years he has pioneered research in design of aspheric and freeform optics for nonimaging and imaging applications, specifically he is coinventor of the SMS optical design method. More recently, Pablo Benitez has cofounded and is CTO of Limbak, which is an IP company developing advanced freeform optics for the forthcoming VR and AR glasses.
