Abstract
The invention relates to a device for the frequency analysis of a signal, comprising a diamond crystal having NV centers defining sub-regions, an excitation unit for optically or electrically exciting each sub-region, an injection unit for injecting a signal so that the sub-region is in the presence of the signal, a magnetic field generator designed so as to generate a magnetic field on each sub-region, the magnetic field having a spatial variation of amplitude in a first direction, and a detector for detecting the resonance frequency of each sub-region of the region, the detector comprising an electrical contact for detecting the charges created in a sub-region, and a reading circuit.
