Electrostatic Detection Apparatus
Electrostatic Detection Apparatus is a methodology used to detect and visualize the indented impressions present on a page of paper. These impressions are the result of the preparation of writing on a document while in contact with the examined page of paper. The content of indented impressions and the identity of their source can allow for the determination of the sequence of preparation of different documents. Therefore an out of sequence document can be shown to have been prepared at a time different from its date.
