| Abstract: | The principle of two dimensional PSD is introduced briefly in this paper and a coaxial measuring model is presented. According to this model, the parallel misalignment and angular misalignment can be calculated so long as light spot coordinate of PSD at two discretionary angles is measured. The system hardware and software flow chart are given. |
