Abstract :
The authors have developed a method by which one can obtain the surface charge pattern and density on the BSO (Bi12SiO20 ) crystal surface by means of the electrooptic Pockels effect of the BSO crystal and a video tape recording system. The measurement of electrical charge distribution on an insulator surface and the discrimination of electrical charge polarity using circular polarized incident light and BSO crystal is demonstrated
