Abstract
We studied the dynamic behavior of director-reorientation induced by linear ly polarized light in an oligothiophene-doped liquid crystal (LC) by transm ission-mode analyses and the Z-scan measurement. An in-plane reorientation process occurred and LC molecules tended to reorient parallel to the polari zation of incident light in the case of low-intensity irradiation. The ther mal effect due to absorption affects the reorientation behavior largely in the case of high-intensity irradiation.
