| Abstract: | In this paper, the characteristics and structure of PSD laser measuring micro-displacement instrument are introduced. According to the equation of input and output as well as the error sources, the accuracy of the instrument is analysed. The system error and random error of the instrument are determinod by processing the data of measurement results. Based on the above-mentionod analysis, we can compensate for errror and improve measurement accuracy of the instrument. |
