| Abstract: | The working principle and characteristic of one dimension PSD are introduced,and a method that uses PSD as position sensor to achieve zero tracking is proposed.According to the method,a series of high speed,high accuracy signal processing circuit,software arithmetic and key technologies are expounded.Some difficult problems of remote vertical transfer in the azimuth angle measurement system are solved effectively,and a less than ±10″ measurement result of general angle transfer error is acquired. |
