  • Atomic magnetometer and method of sensing magnetic fields
    Patent number: 8334690
    Abstract: A magnetometer and method of use is presently disclosed. The magnetometer has at least one sensor void of extraneous metallic components, electrical contacts and electrically conducting pathways. The sensor contains an active material vapor, such as an alkali vapor, that alters at least one measurable parameter of light passing therethrough, when in a magnetic field. The sensor may have an absorptive material configured to absorb laser light and thereby activate or heat the active material vapor.
    Type: Grant
    Filed: August 7, 2009
    Date of Patent: December 18, 2012
    Assignee: The United States of America as represented by the Secretary of Commerce, The National Institute of Standards and Technology
