Freeform Optics explores the evolving impact of freeform optical surfaces on optical systems for both imaging and non-imaging.

Freeform Optics explores the evolving impact of freeform optical surfaces on optical systems for both imaging and nonimaging. 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 nonimaging 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 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
