摘　　要：提出了利用某些透明媒质的Ｆａｒａｄａｙ磁光效应和Ｐｏｃｋｅｌｓ效应的两种光测电功率新方法．讨论了这两种方法的原理及信号处理方法．与传统的测量电功率方法相比，这两种光测方法所采用的系统具有体积小、重量轻、动态范围大等优点．因此。Two of new optical methods for measuring electric power utilizing the Faraday’s magneto optical effect and the Pockels effect of some transparent materials are proposed. The principles and signal processing technique of the two methods are discussed. Compared with the traditional metheds for measuring electric power, the methods show that the measuring systems are small in size, light in weight, and wide in dynamic range. Therefore, it is quite possible to be used in electric systems.
