Title: Robert A. Lewis and His Marine Lidar Invention.

Introduction

Robert A. Lewis is an inventor associated with Flagstaff, Arizona, and Garmin International, Inc. His patent work includes a marine lidar system designed to support three-dimensional laser scanning. The available information identifies 1 patent associated with him.

Latest Patents

Lewis’s listed patent, “Marine Lidar System,” describes an ultra-compact optical receiver for laser scanning. Its narrow field of view can track a moving transmit beam, helping isolate reflected signals from sunlight and other interfering signals that can reduce sensitivity.

The system uses a Digital Light Projector (DLP) micromirror array to select portions of the receiver’s field of view. Mirrors in the “pass” state direct selected light toward the optical detector, while mirrors in the “dump” state direct unwanted light away. A total internal reflection prism configuration routes incoming light to the array and directs light from the two mirror states toward either the detector or light-absorbing regions.

Career Highlights

The marine lidar patent reflects Lewis’s work on optical receiver design and signal management for three-dimensional scanning. His listed company affiliation is Garmin International, Inc.

Collaborations

The provided information names Joseph R. Bietry and Heidi Leising Hall as Lewis’s coworkers. It does not specify their roles in the patent or describe particular collaborative projects.

Conclusion

Robert A. Lewis’s listed marine lidar invention combines a DLP micromirror array and a specialized prism arrangement to help detect reflected laser signals while reducing background and interference.
