Abstract
In the illustrated embodiment of the invention a scanning system is provided for scanning a chargeable surface for latent image detection. The chargeable surface is charged to a first potential, and a scanner probe is charged to a second potential within a predetermined potential difference from the first potential. The scanner probe is oscillated at a selected frequency and reads or measures the oscillation current that is induced from the oscillation and detects any latent images or other electrostatic distributions on the chargeable surface. A processor processes the probe measurements for determining the potential of a latent image on the chargeable surface based on the scanner probe readings.
