Abstract

PURPOSE:To device photo detecting operation point by measuring optical anisotropy through the use of an analyzer whose polarizing direction is deviated by a specified angle. CONSTITUTION:Linearly polarized light or elliptically polarized light by a polarizer 2 whose polarizing direction is vector P makes double refraction according to the optical anisotropy of the sample 3 to which a magnetic field is being applied and this light passes through an analyzer 4 whose polarizing direction is vector A and becomes the quantity of light proportional to the square of sine wave of the magnitude of the anisotropy. This light is received in a photo detector 6. If the analyzer whose polarizing direction vector has been so deviated as to become smaller than the 1/2 of the maximum value of this quantity of the received light and larger than its minimum value and to a polarity opposite from the rotating angle by the anisotropy of the sample 3 is used, the photo detecting operation point of the non-sample state by the photo detector 6 is deviated. Hence, the change in the quantity of light increases according to anisotropy and this enables measurement sensitivity to be improved. The similar results may also be obtained even by providing a rotatory element immediately before the analyzer without deviating the polarizing vector direction of the analyzer.
