【Abstract】 The analysis of an optical system that is designed for obtaining the relative rotary movement azimuth information between the transmitter and the receiving settings is reported. By using the LiNbO3 crystal’s linear electro-optic effect we have deduced the relationship between the intensity difference of the outgoing o ray and e ray and the relative rotary angles of the transmitter and the receiving settings. Some possible errors have also been analyzed.更多还原
