【Abstract】 The polarization interferometry with high resolution and high accuracy is widely used in the measurement of geometrical quantities. In this paper, the measuring errors of this method have been analysed by use of strict mathematical means, and the ways for compensating or reducing these errors are also proposed.更多还原
