摘　　要：应用电路模拟软件Multisim对四边形结构、方形结构、直角形结构、双面结构位置敏感探测器的线性度进行仿真实验研究,得到了相应的线性网格图,并进行了分析.综合比较这几种不同结构二维位置敏感探测器的线性度.结果表明:四边形电极结构位置敏感探测器的位置误差最大,中央40%光敏区的位置误差约为10.05%,直角型电极结构位置敏感探测器,双面型电极结构位置敏感探测器以及带电阻边框的方形电极结构位置敏感探测器在相应区域的位置误差的误差分别为3.70%,0.29%,0.12%.对计算结果与试验结果进行了比较,表明该方法具有简单直观,参量变化多样性,结果可靠的优点.Four structure types of two dimensional position sensitive detectors have been studied. There are the tetra-lateral PSD, the modified tetra-lateral PSD , the duo-lateral PSD and the resistance bordered PSD. The RC models of these four structure type PSDs have been developed and the l＇inearity of them are emulated by the soft of the Multisim. The linearity position grid and the errors graphics show that the average error in the 40% centric sensitive area of the tetral-lateral PSD, the modified tetra-lateral PSD , the duo-lateral PSI） and the resistance bordered are 10.05%, 3.70% ,0.29% and 0.12% respectively. The result shows that the models can give a more exact analysis on different structure types of two dimensional position sensitive detectors than the analytic and numerical methods.
