Description: A crop from File:Xerox Optical Mouse Chip.jpg showing the chip more clearly. The dark square in the left half of the chip is the 4x4 array of photodiodes, with 16 wires connecting each to each of the top and bottom edges. One edge is for test inputs, to discharge the photodiode electrically to simulate light input on a tester, while the other edge is the photodiode outputs to the logic.
