At present, the territory is more and more that scientific research make use of polarized light magneto-optic effecting, for example , studying magnetic of universe , observing the structure of microcosm magnetic , and so on. A variety of optical instrument and measurement sensor are made by magneto-optic effect, usually the new technology is superior to the former.At the same time, some researcher study the magnetic of sun on the basis of magneto-optic effect. However, there have been few reports on the magnetic by means of this theorem in the world. Li xiaojun vice-researcher that is my tutor has expounded a new methodology to measure magnetic on the basis of it. By the new methodology that one researches the magnetic in order to pursue three-dimensional space photographing for the magnetic, we can overcome much limitation in the measurement magnetic on hand, and we can improve the measurement efficiency.A part of experiment are expounded in the paper, which is about magneto-optical image technology for magnetic, and so the purpose offer some reliable data and some effective experiment project for it, besides searching to be on to achieve the technology. The main research is follows:1. This paper summarizes the development, application of polarized light and magneto-optical rotation effect technology at present.. It especially introduces the theorey and feature about magneto-optical image technology in magnetic, and introduces some task to be on later.2. Since the incident ray which magneto-optic effect brings about is polarized light, this paper introduces how polarized light happens and Brewster law, and accounts the polarized peculiarity experiment which reflects sun's rays from the face of the earth. Then the result is assayed in detail, which can determine the direction of photographing detector of magnetic.3. The material base is magneto-optic material that Faraday magneto-optic effect brings about, which is the result that plane polarized light interact between magneto-optic material. So the paper introduces the principle of magneto-optic effect, and the dielectric magneto-optic rotation experiment and about measuring magnetic which we have done, then researches Verde constant law by different kinds of factors.4. Our purpose is that three-dimensional space magnetism message will be got by the magneto-optical image technology at last. However, at first it must be resolved two-dimensional space photographing . For this reason, it have been carried out two-dimensional space photographing for the zone magnetic in laboratory primarily. At present we have obtained two-dimensional space photographing for the partial magnetic field from magnet, and have calculated the weight of magnetic induction at the ray direction.
