US Patent:

7450065, Nov 11, 2008

Filed:

Jun 21, 2006

Appl. No.:

11/472722

Inventors:

Gregory S. Bruce - Abington PA, US
Timothy R. Riley - Delran NJ, US
Wilbur Lew - Mount Laurel NJ, US

Assignee:

Lockheed Martin Corporation - Bethesda MD

International Classification:

H01Q 3/00
G01S 7/40

US Classification:

342360, 342173, 342372

Abstract:

A radar system operates at various different frequencies, and routes power among various antennas by use of a hybrid arrangement. The system is precalibrated at each possible operating frequency by adjusting the phase shifts associated with the hybrid in a feedback manner to provide optimal performance, and the calibration values are stored. During normal operation, the calibration values of phase shift are selected and used for feedforward operation at each frequency.

International Classification:

G01R 33/26
G01R 33/00

Abstract:

The present disclosure relates to apparatuses and methods for stimulating a magneto-optical defect material with defect centers in a magnetic detection system using a stimulation process to significantly increase magnetic sensitivity of the detection system. The system utilizes a Ramsey pulse sequence pair or a shifted magnetometry adapted cancellation (SMAC) pair to detect and measure the magnetic field acting on the system. Utilizing a pair of magnetic measurements that are approximately in quadrature improves the dynamic range and accuracy of the magnetic detection.

Inventors:

- Bethesda MD, US
Gregory Scott Bruce - Abington PA, US
Nicholas M. Luzod - Seattle WA, US

Assignee:

Lockheed Martin Corporation - Bethesda MD

International Classification:

G01R 33/032
G01R 33/26

Abstract:

A sensor is described comprising a waveplate assembly, an optical excitation source and a magneto-optical defect center material with defect centers in some embodiments. The waveplate assembly can include a waveplate, mounting base, and a mounting disk. The mounting disk can be adhered to the waveplate. The mounting base can be configured such that the mounting disk can rotate relative to the mounting base around an axis of the waveplate. The waveplate can be used to tune the magnetic field measurement for certain axes materials by controlling the polarization of light entering the magneto-optical defect center material or to conduct a calibration of the system.

International Classification:

G01R 33/032
G01J 1/58
G01R 33/00

Abstract:

A magnetometer includes a light source that provides excitation light and a magneto-optical defect center material with at least one defect center that transmits emitted light when excited by the excitation light. The magnetometer also includes a light sensor that receives the emitted light and a plurality of magnets that provide a bias magnetic field to the magneto-optical defect center material. The magnetometer further includes a ring magnet holder that has an outer ring with an outside surface and a plurality of holders extending from the ring. The plurality of holders hold the plurality of magnets in a same orientation with respect to one another. The magnetometer further includes a mount that has an inside surface. The outside surface of the outer ring slides along the inside surface of the mount.
