I wonder if the same approach that has been found for touch sensors
may apply here to. That is can the Csd Sensors be connected is parrallel
to a couple or three series resisters. Then when light hits the left
sensor it generates a number and when the light hits the right sensor a
different number is generated, and so forth.
