Abstract
The device for imaging finger prints has a transparent electrically insulating substrate, a thin transparent electrode on the substrate and a sensitive layer on the electrode comprising electroluminescent dielectric material, arranged to receive hand tissues whose print is to be imaged. A source means connected to said electrode applies a voltage between the electrode and tissues. A camera provides a picture taken through the substrate.
