Imaging grain microstructure in a model ceramic energy material with optically generated coherent acoustic phonons
Optically generated acoustic phonons have enabled depth resolved microstructure characterization. Here, the authors extend this method to obtain information on the orientation of individual crystallites by studying influence of probe beam polarization on detected signal amplitude.
