METHOD FOR FAST RECORDING OF MULTIDIMENSIONAL SPECTRA IN RADIOSPECTROSCOPY

摘要

FIELD: physics. ^ SUBSTANCE: sample is exposed to a pulse sequence with independently varying time intervals. The number of measured points on time intervals is reduced via non-uniformly successive sampling without shortening the sampling length. Multidimensional Fourier transform is performed via numerical integration, wherein discretisation of time variables is performed adaptively to the signal amplitude, while increasing the sampling step and reducing intensity of the picked up signal. ^ EFFECT: shorter time for recording multidimensional spectra while maintaining high resolution. ^ 3 dwg
