使用光波导调制器制成了高分辨率测距仪。光调制器的调制频率约为3.5GHz，而光强度的调制频率约为7GHz，因为调制偏置电压被设置为电光特性的峰值点。测距仪在 NRLM 隧道中进行了评估。在校正循环误差后，对于 0.5 m 至 5 m 的距离范围，测量分辨率为 15 微米的标准偏差。
A high resolution distance meter has been made using optical wave-guide modulators. The modulation frequencies for the optical modulators are around 3.5 GHz, while the modulation frequencies of optical intensity are around 7 GHz because the modulation bias voltages are set to peak points of the electro-optic characteristic. The distance meter was evaluated in the NRLM tunnel. The measurement resolution is 15 micrometers of a standard deviation for a distance range of 0.5 m to 5 m after a correction of a cyclic error.
