利用光电位置敏感元件ＰＳＤ作为传感器，研制了石英摆片综合参数测试系统，本文对该系统的测试原理进行了详细的介绍．该系统可对石英摆片的摆幅、扭幅、摆频、扭频及挠性梁的刚度等实现自动测量．
Using the photoelectric position sensitive element PSD as the sensor, a comprehensive test system of the quartz pendulum piece was developed. The principle of this system was introduced in detail in this paper. The system can automatically measure the swing amplitude, torsion amplitude, swing frequency, torsion frequency and flexural rigidity of the quartz pendulum.
