摘要： A phase plate is superposed on a sample, and this phase plate is so adjusted that the phase difference of the total retardation of the sample and the phase plate is integral times 2.pi. with respect to a measuring beam of a first wavelength, so that retardation can be correctly measured even if an order is increased. In this state, a measuring beam of a second wavelength which is approximate to the first wavelength is employed and two polarizing plates maintaining polarizing directions in parallel nicol relation are singularly rotated with respect to the sample which is arranged therebetween. The ratio Im/Io between maximum value Io and minimum value Im of currently transmitted light intensity is applied to a previously prepared relation between the order n of retardation and this ratio Im/Io to derive the order of retardation of the sample, to thereafter obtain correct retardation.

摘要： A system and method for determining the anisotropy of a sample of a light transmitting sheet is disclosed. The surface of the sample is irradiated with a polarized light which is directed through the sample to an analyzer element. The polarizing plane of the analyzer is matched to, or maintained in a predetermined angular relation to, the polarizing plane of the polarized light. The sample is rotated relative to the analyzer element so that the optical anisotropy can be determined from the relationship between the rotation angle and the output of measured light.

摘要： The combination of a polarizer and an analyzer, and a sample interposed therebetween are rotated relative to each other to determine the relationship between the angle of rotation and the intensity of light transmitted through the arrangement. The birefringence of the sample is obtained from the retardation values calculated from the result of the determination. When the determination is made for two kinds of light with different wavelengths close to each other, the retardation can be determined straightforwardly. When at least three kinds of light with different wavelengths are used for the determination, different retardation values are obtained for the respective wavelengths for a highly accurate analysis.

摘要： In order to efficiently obtain data for calculating retardation values at a plurality of wavelengths, a sample having birefringence is placed between a polarizer and an analyzer, which are maintained in a parallel nicol relation to each other and rotated about an optical axis of measuring light. White measuring light is applied through the polarizer so that the light being passed through the sample and transmitted through the analyzer is received by a polychromator. A one-dimensional optical sensor is arranged on an outgoing imaging surface of the polychromator, to simultaneously detect transmitted light intensity values of a plurality of wavelengths. Since transmitted light intensity values of a plurality of wavelengths are obtained every polarization rotation angle of the polarizer and the analyzer, it is possible to obtain dispersion of retardation values with respect to wavelengths and the like by processing the data.
