I think is roughly a point light source in most Nikon scanners, but it
may be a more diffuse array of LED's in the LS-8000 (but not
a linear array of LED's).

I'm not positive how they're organized, but I suspect they're three lines
in a single CCD chip, with a separation of either 8 or 12 pixels
between the lines (this is how most scanners work).

The scanner exposes all three CCD lines with Red, then all three with Green,
all three with Blue, then all three with Infrared.
