| Abstract: | According to the noise source and characteristics of the position sensitive detector (PSD),an adaptive inhibition method based on FIR Wiener filter is proposed.The Wiener filter is used as digital filter and transmission characteristics are adaptively adjusted to improve the signal to noise ratio of PSD so that the accuracy of measurement in PSD application system is greatly improved. |
