| Abstract: | The principle for phase laser ranging system is discussed. The whole design of circuit system is put forward. The method of digital phase detecting and implementation are introduced in details. The schematic diagram of phase detecting is given. Higher detecting accuracy is able to be obtained because of the high speed and wide band width of CPLD. |
