Join our presentations on TrueFreeform

Presentation: TrueFreeForm: A novel approach to freeform optimization
Date: Monday 24th June 2019, 11:00 - 11:20
Location: Hall B2 Stand B2.356

Description: Zemax Optical Engineer Zach Derocher is pleased to introduce TrueFreeform™, the latest method in designing freeform optics that will be included in OpticStudio later this year. As opposed to using a linear combination of Zernike functions, TrueFreeform uses a grid-based surface where sag contributions are specified on a rectangular grid, allowing local influence on a specific region of the surface that is only as wide as twice the grid spacing. Grid-based surface optimization allows flexibility in designing freeform optical components that is not possible with traditional surface types.

Presentation: A novel approach to freeform optimization: designing an eye-tracking augmented reality system using grid-based sag optimization 
Date: Tuesday 25th June 2019, 8:00-10:00
Location: Hall B2 Stand B2.356

Description: As manufacturing capabilities have developed, the potential to create complex geometries for optical elements of a variety of materials has become a reality. Under these conditions, freeform optical components have become more prevalent in the industry and have allowed a new class of optical systems to be engineered. In the past, freeforms have commonly been described parametrically for optimization, which in some cases limits their flexibility and utility. In this paper we demonstrate a novel freeform design methodology which uses a grid-based sag definition to serve as an alternative to polynomial coefficient optimization. The OpticStudio TrueFreeForm model allows direct optimization of sag values at grid points across the surface to enable spatially-selective surface sag optimization. Zemax Optical Engineer Zach Derocher will present a case study on the effectiveness of TrueFreeForm optimization in the design of freeform optical surfaces for use in modern augmented reality/virtual reality (AR/VR) optical systems. He will demonstrate the flexibility and advantages of grid sag optimization and discuss key implementation considerations in the context of a freeform wedge prism system as might be found in an AR headset. In particular he will demonstrate, via sub-aperture grid sag optimization, the integration of an eye-tracking subsystem into the AR wedge prism. An average MTF of 0.446 at 40 lp/mm is achieved in the user pupil imaging portion of the eye-tracking system, while introducing no degradation in the nominal performance of the AR visual display system.

Join our presentation on High-Yield Optimization

Presentation: High-Yield Optimization 
Date: Tuesday 25th June 2019, 13:40-14:00
Location: Hall B2 Stand B2.356

Description: Zemax OpticStudio Product Manager Thomas Pickering will present High-Yield Optimization as a new fast, efficient method for improving as-built optical designs. High-Yield Optimization, which will be included in OpticStudio this year, produces radically different design forms from best nominal forms that ignore manufacturing defects.
