Introduction

Chad Fertig is an inventor based in Roseville, Minnesota, whose patent work addresses the design of atomic magnetic sensing systems. His listed patent is assigned to Honeywell Aerospace US LLC.

Latest Patents

Fertig is credited with 1 patent: “Techniques for Atomic Magnetometers and Atomic Magnetic Gradiometers.” The invention uses at least one photonic integrated circuit (PIC) to reduce the size, weight, and cost of the vacuum chamber used in an atomic magnetic sensor, and consequently of an atomic magnetometer or gradiometer. The PIC receives an optical signal, such as one from a laser, and distributes it to one or more sets of grating-coupled surface emitters. Each emitter collimates, directs, and emits an optical beam derived from part of the signal toward an optical detector.
