Claim 4:
5. The method of claim 1, wherein the step of subjecting the sample to a spin magnetometry measurement with the point defects-based spin magnetometer to generate a string or an array of the spin measurement results of said sample further comprises:
a) placing the sample in a static magnetic field which permeates the sample and polarising or hyperpolarising at least some nuclear spin moments of the sample along the magnetic field for creating longitudal magnetisation;
b) converting said longitudal magnetisation into transverse magnetisation by irradiating frequency pulses with a 90° flip angle, thereby influencing said nuclear spin moments;
c) irradiating a sequence of high-frequency pulses having an initial pulse and a final pulse onto at least one detection spin moment, thereby influencing said detection spin moment, and subsequently recording a signal of said transverse magnetisation present in a detection region of the sample; and
d) repeating c) several times in succession, wherein said initial pulse and said final pulse of said each sequence have a pulse phase which is the same.
