Abstract
An imaging device comprising a linear illumination source having two ends and operable to radiate light onto a scan object, the illumination source radiating light along a length thereof, the light radiated from the illumination source having a minimum intensity at a midpoint thereof and a conversion element operable to convert light into electric charges corresponding to an image is provided. A method for imaging a scan object comprising radiating light from a linear illumination source having two endpoints onto the scan object, the light radiated from the illumination source having a maximum intensity at the two endpoints of the illumination source and a minimum intensity at a midpoint of the illumination source is provided.

An imaging device, comprising:
- a linear illumination source having two ends and operable to radiate light on a scan object, the illumination source radiating light along a length thereof, the light radiated from the illumination source having a minimum intensity at a midpoint thereof;
- and
- at least one conversion element operable to convert light into electric charges corresponding to an image.
A method for imaging a scan object, comprising radiating light from a linear illumination source having two endpoints onto the scan object, the light radiated from the illumination source having a maximum intensity at the two endpoints and a minimum intensity at a midpoint of the illumination source.
An imaging device, comprising an illumination source having two ends and operable to radiate light on a scan object, the illumination source having a luminescent substance distributed along a length of the illumination source, a density of the luminescent substance greater at the ends of the illumination source than at a midpoint of the illumination source.
