Abstract
Abstract The contribution presents the state of the art in Nuclear Magnetic Resonance (NMR) — applications developed in our institute in the last two years. We have started our investigations using spectral information for the determination of aging states of different commercial prepreg materials Our NMR-system is a Broker MSL 400 solid state spectrometer with magic angle spinning device (MAS) and with micro imaging facilities which allow in a first step only the imaging of biological tissues. The system (superconducting coil) works with 9.4 T magnetic field corresponding to a resonance frequency of 400 MHz for 'H nucleus spins. The magnetic field gradient for imaging has a maximum strength of 70 G/cm In order to optimize the system for solid state imaging applications different techniques were implimented. Beside the well known Fourier-Transform-Imaging-algorithm with frequency and phase information, a back-projection-algorithm and a Fourier-Transform-Imaging-algorithm using only phase information now a...
