The Paul wavelet algorithm was prepared as a method to obtain the birefringence values continuously for a liquid crystal sample by using the transmittance spectrum in visible and near-infrared regions at room temperature. The obtained results determined from the Paul wavelet algorithm are harmonious with the 5CB-coded liquid crystal catalog value and the results determined from the fringe counting method. The controlling on the resolution of the working space is possible with the Paul wavelet, and the presented work attempts to depict the importance of control. Noise effect and absolute errors of the presented method and the fringe counting method are also studied and compared.
