Microscopic response in thermoplastic-photoconductor media (edge effect)

Abstract
An edge effect in thermoplastic-photoconductor media has been studied and it is found that the edge effect is in proportion to both the light intensity and the spatial frequency of the (holograms, and is more remarkable in the PLA method than the conventional simultaneous method. These results suggest that the edge effect is caused by the electric field which is bent by the uneven surface charges, the trapped charges and the localized charges in the photoconductor medium.
