Figure 2 depicts a cross sectional pictorial of the module. Mounted in the module is a one-to-one graded indexed micro lens array that
focuses the scanned documents' image onto the chip's sensing line. The sensing line is located along the module's sensor axis, known
as the read line. These photon images are transformed into proportional video charges and processed by two on-board amplifiers. The
video signal from the amplifier transmits a sequential stream of video pixels to the video output pin of the AMIS-710324-A4 module.
Also mounted in the housing is a LED light source. Figure 2 shows the LED bar and its illumination path. The path traces the ray from
the LED and is reflected from the document and focused through the ROD lens and onto the sensors. All these components are housed
in a small plastic housing with a cover glass. The cover glass serves as a window with the outside surface as the focal point for the
image on the document. It also serves to protect the imaging array, the micro lens assembly and the LED light source from dust.
