TRANSIENT HEATING BEHAVIOR IN PLANAR NEMATIC LIQUID CRYSTAL USING PHASE RETARDATION METHOD
相位延迟法液晶沿面排列瞬态热效应

By means of the optical phase retardation method the YAG laser was used to observe the transient heating behavior in planar nematic liquid crystals. According to the experimental results, heating effect may induce molecular reorientation in liquid crystals. Azo-dye and photoisomerized-dye in planar nematic liquid crystals have little effect on heating behavior, but the liquid crystal doped with chiral molecules shows temporary memory effect.
