Abstract

A method of imaging an object comprising emitting ultraviolet light having a single intensity on the object, converting light fluoresced by the object into electrical charges comprising a scanned image of the object, and generating a data set defining the scanned image is provided. An apparatus for imaging a document surface comprising a first illumination device operable to emit ultraviolet light of a single intensity onto the document surface, and a photosensitive device operable to receive fluoresced light emitted by the document surface and convert the received light into electrical signals comprising a scanned image of the document surface is provided.

Claims (16)

1. An imaging system, comprising:

a carriage movable relative to an object disposed against a platen;

an illumination device attached to the carriage and adapted to emit ultraviolet light toward the object; and

a photosensitive device adapted to receive light reflected by the object for generating a scanned image of the object.

2. The system of claim 1 , wherein the illumination device comprises a fluorescent black light tube.

3. The system of claim 1 , further comprising another illumination device attached to the carriage and adapted to emit visible light toward the object.

4. An imaging apparatus, comprising:

a platen for supporting an object;

an illumination device operable to emit ultraviolet light toward the object; and

a photosensitive device operable to receive fluoresced light emitted by the object and convert the received light into electrical signals comprising a scanned image of the object;

and wherein the illumination device is disposed on a carnage of the imaging apparatus.

5. An imaging apparatus comprising:

a platen for supporting an object;

an illumination device operable to emit ultraviolet light toward the object; and

a photosensitive device operable to receive fluoresced light emitted by the object and convert the received light into electrical signals comprising a scanned image of the object; and

another illumination device operable to emit visible light toward the object.
