Abstract

T-Glasses is LetinAR’s truly eyeglasses-shaped lightweight augmented reality device which uses plastic optical combiners. Thanks to its unique PinTILT (Total Internal reflection minimized Lightguide Technology) structure, it shows moderate optical manufacturing tolerance allowing injection molding suitable for low-cost mass production. In this talk, Dr. Park introduces the latest advancement of PinMR (Pin Mirror) optical structure: PinTILT, and how it can minimize the number of total internal reflections by adopting a modified birdbath structure, which results in the minimal form factor of AR glasses.
