Composite optical modulation of electro-optical effect with magneto-optical effect and application

With the method of JOnes matrix, formulas for intensity of transmitted light through the optical analyzer of various composition of electro-optical effect with magneto-optical effect are derived. The results show that the output beam from the analyzer carriers information on current, voltage, active power and apparent power. We can use the electric filter circuit to pick out this information for measuring active power, apparent power etc. The paper discusses what quantities measured when the analyzer set on certain definite values, and points out the optimum selection for various measurements.
