摘要：
A differential optical reflectivity measurement technique for freestanding films is presented. The system is highly sensitive to changes in the polarization state of the reflected light. The method is used to study the evolution of an optically anisotropic liquid crystalline structure with temperature. In addition we present a reflectivity method for determining the film thickness for films consisting of two to hundreds of layers. (C) 2000 American Institute of Physics. [S0034-6748(00)04108-3].
