Sensitivity Analysis of a Position Device with Quadrant Photodiode
... The principle of QPD positioning is simple. Incoming light is focused on the detector as a spot. Comparing of the output currents received from each of the four quadrants, the position of the spot on the surface can be determined. Thus, in general, photo-detection system can be functionally divided ...
