A system for magnetic detection includes a nitrogen vacancy (NV) diamond material comprising a plurality of NV centers, a radio frequency (RF) excitation source configured to provide RF excitation to the NV diamond material, an optical excitation source configured to provide optical excitation to the NV diamond material, an optical detector configured to receive an optical signal emitted by the NV diamond material, and a controller. The optical signal is based on hyperfine states of the NV diamond material. The controller is configured to detect a gradient of the optical signal based on the hyperfine states emitted by the NV diamond material.

DNV magnetic field detector

A system for magnetic detection includes a nitrogen vacancy (NV) diamond material comprising a plurality of NV centers, a magnetic field generator that generates a magnetic field that is applied to the NV diamond material, a radio frequency (RF) excitation source that provides RF excitation to the NV diamond material, an optical excitation source that provides optical excitation to the NV diamond material, an optical detector that receives an optical signal emitted by the NV diamond material, and a controller. The controller is configured to compute a total incident magnetic field at the NV diamond material based on the optical signal emitted by the NV diamond material, and drive the magnetic field generator to generate a compensatory magnetic field, the generated compensatory magnetic field being set to offset a shift in the optical signal emitted by the NV diamond material caused by an external magnetic field.

Apparatus and method for closed loop processing for a magnetic detection system

Methods and configuration are disclosed for providing higher magnetic sensitivity magnetometers through fluorescence manipulation by phonon spectrum control. A method for increasing the magnetic sensitivity for a DNV sensor may include providing a diamond having nitrogen vacancies of a DNV sensor and an acoustic driver and acoustically driving the diamond with the acoustic driver to manipulate a phonon spectrum of the DNV sensor. A DNV sensor may include a diamond having nitrogen vacancies, a photo detector configured to detect photon emissions from the diamond responsive to laser excitation of the diamond and an acoustic driver configured to manipulate a phonon spectrum for the DNV sensor by acoustically driving the diamond.

Apparatus and method for hypersensitivity detection of magnetic field

A method and system for enhancing a radar image provides for application of digital imaging processing techniques to a range-Doppler image produced by a radar system. The application of digital processing techniques includes a 2-D band-pass filter including a smoothing filter followed by a differentiating filter applied to the image. A constraint on concavity is placed upon the resultant 2-D band-pass filtered image to create a mask. The application of this mask to the original image results in an enhanced range-Doppler image with increased resolution.

Image filtering and masking method and system for improving resolution of closely spaced objects in a range-doppler image

A method for displaying information relating to the range and Doppler of a remote target includes transmitting electromagnetic energy toward the target, and receiving reflected signals defining a two-dimensional (range-Doppler) radar image. The reflected signals are matched-filtered, which tends to blur the image. The image is deblurred while the features of thermal noise enhancement and irregularity of the deconvolved output are constrained to produce a single point deblurring output.
