The orientation of liquid crystaland defects included in it can be evaluated by the observation of the reorientation process after the orientation is distorted by a pulse light. In this study, we utilized transient grating method, by which photochemical change can be observed by way of the refractive-index variation. The used sample is (N-(4-methoxybenzylidene)-4-butylanil-ine: MBBA), which is a typical nematic liquid crystal. The reorientation dynamics was observed and we found the orientation change depending on the light intensity, and we proposed a domain of the liquid crystal was reoriented for the higher pump intensity.
