Freeform Optics (Freeform)

07 June 2015 – 11 June 2015 OSA Virtual Event

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.

With the ever expanding successes from the introduction of freeform surfaces into both imaging and nonimaging (illumination) optical systems, there is innovative work being done in both academia and industry in all areas of optical system evolution including,

  • Optical design
  • Optical system simulation
  • Surface representation
  • Fabrication
  • Metrology
  • Optical system assembly
Invited speakers from both industry and academia will speak to the latest developments in these topics and more. 

  • The latest optical designs based on introducing freeform surfaces in lithography, imaging systems, and spectrometers
  • Illumination Systems that are improved or enabled by freeform surfaces
  • Recent examples of fully realized optical systems that utilize freeform optics

John Mather

NASA’s Goddard Space Flight Center, USA
Nobel Prize in Physics 2006
The James Webb Space Telescope 

NASA’s James Webb Space Telescope (JWST), planned for launch in October 2018, utilizes high performance imaging optics to see beyond what the great Hubble Space Telescope can see, farther away and farther back in time.   It will be the workhorse telescope for a generation of space astronomers, opening the infrared (0.6-28 µm) window with a 6.6 m aperture cold telescope. To test it end-to-end, we have developed remarkable laser interferometer technologies, with computer-generated holograms to test the primary mirror, and it must all be done cold and in a vacuum tank.  I will outline the mission design, the scientific objectives, and the current status.

John Mather is a Senior Astrophysicist and is the Senior Project Scientist for the James Webb Space Telescope at NASA’s Goddard Space Flight Center (GSFC) where his research centers on infrared astronomy and cosmology.  He led proposal efforts for the Cosmic Background Explorer (COBE), which ultimately enabled the COBE team to show that the cosmic microwave background radiation has a blackbody spectrum within 50 parts per million, confirming the expanding universe model (the Big Bang Theory) and initiating the study of cosmology as a precision science. The COBE team also first mapped the hot and cold spots in the background radiation (anisotropy), now attributed to quantum fluctuations in an inflationary period in the first 10-36 sec of the universe; Stephen Hawking called their discovery “the most important scientific discovery of the century, if not of all time.”

Shree Nayar

Columbia University, USA

Advances in Computational Imaging
Computational imaging uses new optics to capture a coded image, and an appropriate algorithm to decode the captured image. This approach of manipulating images before there are recorded and processing recorded images before they are presented has three key benefits. First, it enables us to implement imaging functionalities that would be difficult, if not impossible, to achieve using traditional imaging. Second, it can be used to significantly reduce the hardware complexity of an imaging system. Lastly, under appropriate imaging conditions, it allows us to break the limits of traditional imaging. In this talk, I'll show recent examples of cameras that demonstrate these benefits.

Shree K. Nayar is the T. C. Chang Professor of Computer Science at Columbia University. He heads the Columbia Vision Laboratory (CAVE), which develops advanced computer vision systems. His research is focused on three areas - the creation of novel cameras that provide new forms of visual information, the design of physics based models for vision and graphics, and the development of algorithms for understanding scenes from images. His work is motivated by applications in the fields of digital imaging, computer graphics, robotics and human-computer interfaces.

Nayar received his PhD degree in Electrical and Computer Engineering from the Robotics Institute at Carnegie Mellon University. For his research and teaching he has received several honors including the David Marr Prize (1990 and 1995), the David and Lucile Packard Fellowship (1992), the National Young Investigator Award (1993), the NTT Distinguished Scientific Achievement Award (1994), the Keck Foundation Award for Excellence in Teaching (1995), the Columbia Great Teacher Award (2006), and the Carnegie Mellon Alumni Achievement Award (2009). For his contributions to computer vision and computational imaging, he was elected to the National Academy of Engineering in 2008, the American Academy of Arts and Sciences in 2011, and the National Academy of Inventors in 2014.
