Aiming at the problem of the quadrant photodetector precision,this paper researches the error of different spot model,analyzes the difference of uniform spot and Gauss spot.Simulation is done by utilizing image processing technology and emulator technology.The result of simulation shows that the error always exists no matter what spot model is used and the errors are calculated.It provides important reference for engineering application.
