摘要： In an optical anisotropy measurement apparatus for emitting a light flux from a He-Ne laser to be incident to an object to be examined, such as a liquid crystal in a liquid crystal cell, and detecting a light flux totally reflected from the object to be examined to measure an optical anisotropy of the object, a portion of the incident light flux is designed to be incident at an angle smaller than a critical angle of total reflection to and transmitted through the object to be examined. As a result, a light flux-incident region causing total reflection at the boundary is allowed to have a shape closer to a circle and have a smaller size, thus allowing detection of a local alignment change in optical anisotropy as caused by, e.g., a minute alignment defect in a liquid crystal device. Further by detecting the transmitted portion of the incident light flux, an optical anisotropy of the object to be examined at a position other than a boundary thereof can be measured simultaneously.
