Paper Abstract

The designing principle's analysis and the structure design using modern accuracy design concept of nanometer two dimension working table are introduced. The source of the uncertainty is overall analyzed. The error separating and correcting method is designed. The influence on the measurement result of the autocollimator and the interferometer produced by the angle error of the orthogonal prism is analyzed on principle. The preview experiments are done. The results indicate that the light path deflection using orthogonal prism has no influence on the error separating result, but without absolute zero position has obvious influence on the error separating result. The error correcting result shows that the precision demand of nanometer two-dimensional working table can be met.
