Original Abstract

The electro - optical methods include technique of measurement by changing polarization state by electro - optical crystal. Appropriate electrodes are located on electro - optical crystal which behaves as a modulator of laser beam polarization. Principle of this method lies in premise that electric charge generates vector of electric field intensity. When measuring electrode is pasted into electric field, its intensity is registered. Second electrode has to be earthed so we reach defined voltage on electro - optical crystal between the electrodes which depends on electric charge. The relation between electric charge amount and received optical power on photodetector is presented.
