| Popis: | A basic equation for light scattering by anisotropic scatterers in crystals is obtained using the Born approximation and applied to the scattering behaviour from edge dislocations in sapphire crystals. The orientation and polarization direction dependences of the scattered light, measured by laser scattering tomography, are compared with the calculated results and it is confirmed that the scattering is generated by changes in the dieletric constant caused by the strain field around the dislocation lines. |
