Title: Chuan Luo and His Patent for Holographic Stray Light Suppression.

Introduction

Chuan Luo is an inventor associated with Broomfield, Colorado, and Apple Inc. His work includes an invention designed to reduce stray light and improve optical performance in electronic devices.

Latest Patents

Luo is associated with 1 patent, titled “Holographic Stray Light Suppression.” The patent describes an electronic device with a camera, a lens, and gratings positioned over the lens. The gratings diffract light arriving from selected angles while allowing other light to pass through to the lens and camera. By directing unwanted light away from the optics, the system can help prevent artifacts in image data.

The gratings may be uniform or vary across their surface. In some implementations, they can direct unwanted light into a waveguide that carries it away from the optical components. The patent also describes potential use in augmented reality devices, where an eye box may take the place of a camera.

Career Highlights

Luo’s listed patent reflects work on optical technologies for electronic devices. Its approach uses holographic gratings to manage incoming light and reduce interference with image capture or viewing.

Collaborations

Luo’s listed coworkers include Michael Young and Daniel Ott. The patent’s subject matter is associated with Apple Inc.

Conclusion

Chuan Luo’s patent on holographic stray light suppression presents an optical approach for directing unwanted light away from cameras and other device optics.
