摘要：

A novel method of determining the cell thickness and the tr;ist angle of twisted nematic liquid crystal (TNLC) cells by measurement of the Stokes parameters of light transmitted through the cell is presented. The relationships of the Stokes parameters of transmission light to the cell thickness and the tn ist angle are reduced by use oi Jones matrix representation. The cell thicknesses and twist angles of some TNLC cells are determined practically by this simple method. The experimental results indicate that this method is valid. Furthermore; some properties of this method are discussed and an accuracy analysis bu theoretical calculation is undertaken.
