Methods of laser magnetic tomography
Abstract
Two tomographic methods are proposed based on the laser-polarimetric detection of magnetization variations. The first is a version of conventional magnetic-resonance tomography with an additional spatial selectivity provided by a thin laser beam. The second method exploits resonance behavior of the field dependence of the high-frequency (Van Vleck) magnetic susceptibility, which is a common feature of impurity paramagnets. The laser magnetic tomography methods discussed make it possible to examine the internal relief of transparent paramagnets without complicated computer treatment of the data obtained. Spatial resolution of 0.2 mm is experimentally demonstrated.
