Study on the Mechanism of Magneto-optical Modulation Temperature

In recent years, magneto-optical modulation has a wide range of applications and good performance in the fields of azimuth transfer, magnetic field measurement, metal surface damage detection, etc. The core technology is to achieve accurate measurement of the angle by applying the polarization characteristics of light. The magneto-optical modulation system based on this principle belongs to a kind of electrical components. When working, it needs to load a certain current excitation, which causes the temperature of the system to rise, which in turn has a certain influence on the electrical characteristics of the device, and even causes the working state of the system to occur. Change, so in practical applications, temperature factors must be considered. On the basis of fully understanding the structure and working principle of the components, the paper makes a reasonable simplification of the overall structure of the equipment, and obtains the research physical model and numerical heat transfer model. The results show that one of the main heat sources of the system when the solenoid coil and the stainless steel bracket are used, the system temperature is getting higher with the increase of working time.
