Abstract
Electrostatic detection devices (EDDs) utilize charging to visualize indentations on documents. In this study, a voltage probe was used to measure the characteristics of the voltage at the surface of the film covering the document to better understand this electrostatic phenomenon. The ultimate objective of this research was to enable document examiners to obtain better development of indentations. This initial work demonstrated that such measurements are useful for controlling the extent of charging the film.
