The architecture and principle of the one-dimension position sensitive detector(PSD)is illuminated
the causes of non-linearity of PSD are analyzed.Calibrating experiment is done with one-dimension PSD
a model that the non-linearity of PSD is corrected by the BP neural network is established
but precision of results is low.A way that corrects the non-linearity of PSD based on segment treatment and BP neural network is provided.The advantage of the way is proved by exercise
the reliability and accuracy of data measured by the PSD is improved.It is good for expanding the measurement range and improving the precision of the test system.
