Introduction

Roland Piper is an inventor associated with London, Great Britain, and Snap Inc. His work includes an optical device designed for augmented reality or virtual reality displays.

Latest Patents

Piper is credited with 1 patent. His patent, “Optical device,” describes a waveguide-based display system that directs projected light toward a viewer through diffractive optical elements.

A first input diffractive optical element receives light from a projector, couples some of it into the waveguide along a first path, and allows another portion to pass through. A second input element receives that passing portion and couples some of it into the waveguide along a second path. An output diffractive optical element directs light from both paths toward the viewer at different patterns of positions, creating two corresponding sets of exit pupils.

Career Highlights

Piper’s listed patent connects his work with optical technologies for augmented and virtual reality displays. The invention uses multiple light paths and exit pupils to deliver projected imagery through a waveguide.

Collaborations

Piper is associated with Snap Inc. His listed coworker is Arseny Alexeev.

Conclusion

Roland Piper’s patent describes a waveguide-based optical approach that uses diffractive elements and multiple exit pupils for augmented or virtual reality displays.
