Title: David Allen Hopper and Magnetic Imaging with Diamond Quantum Sensors.

Introduction

David Allen Hopper is an inventor associated with Philadelphia, Pennsylvania, and The MITRE Corporation. His patent work concerns using nitrogen-vacancy centers in diamond to measure magnetic fields produced by integrated circuits.

Latest Patents

Hopper is named on one patent, “Digital Lock-In for Magnetic Imaging with Nitrogen Vacancy Centers in Diamonds.” The invention describes systems and methods for measuring integrated-circuit activity using the spatial resolution of optically detected magnetic resonance (ODMR) in nitrogen-vacancy centers.

A quantum diamond microscope can capture images of fluorescence from these centers as an external microwave field varies. When an integrated-circuit device is placed next to the diamond, its magnetic field affects the fluorescence. Measuring those changes can produce a map of the device’s magnetic field.

Career Highlights

Hopper’s listed patent connects quantum sensing techniques with integrated-circuit analysis. The approach uses magnetic-field-dependent fluorescence to visualize activity in electronic devices.

Collaborations

Hopper’s listed coworkers include Dmitro Jaroslau Martynowych and Sean Mitchell Oliver. They are associated with the patent work on magnetic imaging using nitrogen-vacancy centers in diamond.
