【Abstract】 The structure and operation principle of a novel comb-type one dimensional position sensitive detector (PSD) with high linearity were described.The experimental results showed that the non-linearity of a 1mm×12mm comb-type PSD and a conventional block-type PSD were 0.17%F.S.in the range form 80μm to 11980μm and 1.5%F.S.in the range from 160μm to 2860μm,respectively.It also showed that the comb-type one suffered less distortion near the electrodes.The factors influencing the linearity of 1D-PSD were analyzed.The results were discussed.更多还原
