Abstract: PURPOSE:To measure the optical characteristic, especially the double refraction elliptical body which represents the optical anisotropy of a transparent formed object, etc., without breaking the object by analyzing the degree of ellipticalization of incident circularly polarized light. CONSTITUTION:A sample for measurement is put in and fixed to a sample section 11 and the laser light emitted from a light source section 2 is circularly polarized by means of a 1/4 wave plate 4. The polarized light passed through the sample passes through a photodetecting section 6 and reaches a photoreceptor element section 7 where the intensity of the polarized light is detected. While the calibrated disc of the sample section is rotated and set at a fixed incident angle, the photodetecting section 6 is rotated and the maximum and minimum transmitted light quantities are measured by changing the azimuth from 0 deg. to 360 deg. at regular intervals. Then a graph, on which the azimuth is plotted on the horizontal axis and the ratio of the maximum light quantity to the sum of the maximum and minimum light quantities is plotted on the vertical axis, is prepared and the graph is compared with another graph on which factor values are optionally set and found by calculation. When both graphs are compared and collated with each other, the refraction elliptical body can be found.
