Miyake 介绍了改进光脉冲测距精度的方法。用此改进方法的原因之一,是考虑到时间间隔计数器的停止阀电平,由于接收信号强度的变化和距离有关,以半高度停止脉冲调成恒定位置有困难。所以他建议首先测量发射和接收脉冲后沿之间(以及前沿)的时间间隔,然后取其平均值,定出近似的中心。 Miyake introduced ways to improve the accuracy of optical pulse ranging. One of the reasons for this improvement is to take into account the stop valve level of the time interval counter, which is difficult to tune to a constant position with a half-height stop pulse because of variations in received signal strength and distance. Therefore, he suggests measuring the time interval between the trailing and leading edges of the transmitted and received pulses first and then taking the average and setting the approximate center.
