IRRADIATED IMAGES DESCRIBED BY ELECTRICAL CONTACT

摘要

A device generating images described by contact, in which the contact itself closes an open circuit to generate radiation in a pattern corresponding to the contact. The resulting irradiated image corresponds directly to the contact pattern energizing the radiation. In a preferred embodiment enabled by an electroluminescent system without a back electrode, a fingerprint is disposed to close the open circuit by making contact and thereby serving as a "temporary" back electrode. The electroluminescent then energizes in a pattern corresponding to the contact (i.e. the fingerprint) to emit a high-resolution image of visible light with high fidelity to the contact. This visible light image may then be directed on to a photosensitive array standa rd in the art suitable for pixelation and conversion into an electrical signal representative of the image. This signal is available for computerized storage, analysis, processing and comparison.
