摘要
The present invention provides a method for measuring both magnetic and electric fields of a DUT via an electro-optic probing technique at the same time. Also, the present invention provides a method for measuring both electric and magnetic fields via a magneto-optic probing technique simultaneously. The method utilizes the modulation of the position of a probe to measure the electric and magnetic field signals. The DC and AC components of the modulated electric (or magnetic) field signals can be obtained by means of a low pass filter and a lock-in amplifier, respectively. Through a simple calculation, the electric and magnetic field can be obtained simultaneously.
