英文摘要：

The structure and characteristics of duo-lateral position sensitive detector are expatiated,based on which,the generation mechanism of the spatial non-linearity and distortions,especially the edge non-linearity,are analyzed with three-layer feedforward network.A sensitive preamplifier suitable for position sensitive devices and a spectral filter giving birth to bipolar pulse are put forward.Experimental simulations validate the correctness of the proposed method.The application prospect of duo-lateral position sensitive detector in exactitude exploration.
