激光测磁系统的研究

Research on the Magnetic Measurement System by Laser

本文论述了应用激光和法拉第磁光效应传感原理,以崭新的光学方法测量磁场。采用双光路实时比值法,有效地抑制了激光器输出不稳的影响。用单板机进行数据采集和处理,打印输出测量结果。

The paper provides a new method for measuring magnetic field by application of sens-ing principle of Faraday's magneto-optic effect and laser. The system adopts a sensing light and a reference light in real time measurement so as to effectively check the influence of the unsteady output of laser. The data acquisition and processing are carried out by a single board computer.
