Paper Abstract

In this paper, the peculiarity of He-Ne was presented. The structure, working principle, non-linear factors, non-linear processing technology on the position output signal of PSD were analyzed, based on which according to characteristics of position output signal of PSD, the double light pathways optical system and signal processing circuit fit for PSD were designed. The commutation rule of the Gauss laser beam passing thin lens and the best collimation area were analyzed, and then the high-precision laser collimator was developed. Also the constitutes, working principle and characteristics of instrument were generalized and the main technique parameters were presented. Combining the developed straightness error evaluation software and high-precision laser collimator to achieve dynamic and static measurements of straightness error. The experiment results showed the consistency between the theoretic analyses and experiment after the repetitious testing. At last the application foreground of the instrument was prospected.
