Abstract
A scanner system for imaging a transparent media object comprising an illumination source for concurrently illuminating a first and second scan line of a media object, and a carriage comprising a photosensitive device located within the carriage and a light pipe affixed to a surface of the carriage is provided. The carriage is configured to receive on a first region of the photosensitive device light passed through the first scan line and the light pipe is adapted to redirect light passing through the second scan line onto a second region of the photosensitive device. The photosensitive device is operable to sample light directed onto the first and second regions.
