【Abstract】 A method by using eletro optic effect of EO crystal to measure electric field of impulse voltage is given. The basic measurement structures are presented. By means of calculation and comparison, the characteristics of the several varied crystal such as BGO, LN are illustrated. To use HP 8011A impulse signal generator as the signal source, the preliminary testing of the system is made. The experimental results have shown that LN crystal has the characteristics of better sensitivity, linear and frequency compared with the other crystals.更多还原
