Description: 4 pixel camera sensor ‐ angle of incidence
computation
The four pin photodiodes are arranged as shown below and divided into 4 quadrants. Half of the
photo sensitive surfaces of photodiode 1 and 2 belong to quadrant 1, half of the photo sensitive
surfaces of photodiode 1 and 4 belong to quadrant 2, and so on. A simple algorithm determinates in
a first step, in which quadrant the largest amount of light is detected. Then the angle of incidence is
computed.
