| Abstract: | Laser pendulum instrument is designed to measure the swing period of single pendulum using Hall sensor,and the deflexion of the swing side is monitored by a minitype laser on the chassis of the laser pendulum instrument.The instrument has multifunctions of timing,counting and angle measurement,and can detect the rotation of the earth in effective swing time. |

| Keywords: | single pendulum Hall sensor laser period |
