摘要
用微型计算机控制锁相环(PLL)可对计量光栅信号进行数字倍频。用这种技术产生的角度定标脉冲去量度齿轮传动链误差比用时钟脉冲合理,有助于提高光栅仪器的动态检测精度。
The industrial grating signals can be digital frequency multiplication with a phase-locked loop (PLL) controlled by a microcomputer. The angular scaled pulse generated by this technique is more rational than the timed pulse to calibrate the gear drive error. It is of great help to raise the dynamic measurement accuracy of the grating instrument.
