Paper Abstract

A visualization and quantification technique for dynamic surface charge distribution on a dielectric material has been developed based on electro-optic Pockels effect. 2 Using this technique, the surface charge density and distribution can be measured simultaneously, non-contact and non-destructively. Also by using a high-speed video camera(HVC), the dynamic observation of surface charge distribution can be performed. The measurement sensitivity is further improved by optical phase pulse modulation and the cancellation ofthe natural birefringence distribution due to the residual mechanical stress in optical devices, e.g., optical lens. As an example, the dynamic observation of surface charge distribution was performed when ac 8kV high voltage was applied to a needle electrode set perpendicularly on a Bii2SiO2o(BSO) single crystal.
