| Abstract: | The principle of pulse laser ranging is introduced,the two main reasons such as pulse time discrimination error and time interval measurement error,which affect the pulse laser ranging accuracy are analyzed.Aiming at the solution of above two reasons,a higher accuracy method is provided,which uses CR-high pass time discrimination and differential delay line time interval measurement,and its working principle is introduced. |
