43.1 - Invited Paper: Review and Perspective of XR Technologies for Immersive Experience (3:30 PM - 3:50 PM)
-
Hiroshi Mukawa
Sony Semiconductor Solutions Corporation Kanagawa, Japan
-
A number of technologies must be highly integrated to deliver immersive XR experiences to users. These technologies are not only for XR hardware but also for content creation and distribution. In this paper, the authors introduce an XR workflow and review some key technologies. The challenges and perspectives of XR technologies are also discussed.
43.2 - Distinguished Student Paper: Varifocal Augmented-Reality Head-up Display Using Alvarez Freeform Lenses (3:50 PM - 4:10 PM)
-
Yi Liu, Yuqing Qiu, Jiaqi Dong, Bo-Ru Yang, Zong Qin
Sun Yat-Sen University Guangzhou China
-
A varifocal augmented-reality head-up display using Alvarez freeform lenses is proposed. One virtual image can be continuously adjusted between 2.5 and 7.5 m; the other is fixed at 7.5 m. The novel design enables the Alvarez lenses to have apertures larger than 15 cm and a system volume smaller than 10 L.
43.3 - Distinguished Student Paper: Breaking the Optical Efficiency Limit of Pancake Optics in Virtual Reality (4:10 PM - 4:30 PM)
-
Yuqiang Ding, Zhenyi Luo, Shin-Tson Wu
University of Central Florida Orlando FL US
-
Garimagai Borjigin
University of Central Florida & University of Tsukuba & Research Fellow of Japan Society for the Promotion of Science Orlando FL US
-
The authors propose a theoretically lossless pancake optics solution that incorporates a nonreciprocal polarization rotator sandwiched between two reflective polarizers. A proof-of-concept experiment using a commercially available Faraday rotator is implemented. The theoretically predicted 100% efficiency can indeed be achieved approximately by using two high-extinction-ratio reflective polarizers.
43.4 - Invited Paper: Display System Optimization for Augmented-Reality Glasses (4:30 PM - 4:50 PM)
-
Kevin Curtis, Bob Tekolste
Magic Leap Boulder CO US
-
Scott Carden
Magic Leap Austin TX US
-
Kristina Uhlendorf
Magic Leap Jena Germany
-
The diverse range of applications for augmented-reality devices require different hardware features and priorities. For three field-of-view categories — small FoV (15-30°) for basic information display, medium FoV (~50°) for complex information, and large FoV (>65°) for immersive experiences — the authors discuss projector, combiner, and dimmer trade-offs, as well as overall optimization.
43.5 - Invited Paper: Enabling High Performance AR Waveguide Display with Semiconductor Manufacturing Technologies (4:50 PM - 5:10 PM)
-
Samarth Bhargava, Rami Hourani, Yongan Xu, Jinxin Fu, Robert Visser, Ludovic Godet
Applied Materials Santa Clara CA US
-
Surface relief gratings (SRG) - based waveguide has been recognized as the most promising augmented reality (AR) display technology. By leveraging AMAT’s decades of semiconductor process and material engineering experience, together with its advanced design and manufacturing co-optimization capability, the team has produced unprecedented SRG waveguide display quality of high efficiency, high contrast, high resolution, low rainbow effect and great color uniformity. It is a great milestone to enable all day wearable smart AR glasses of low weight and small form factor.
