报道了移频反馈激光器在光学测距中的应用。FSF激光输出由周期性产生的啁啾频率分量组成，其啁啾速率快于100 PHz/s（P=10/sup 15/）。通过利用FSF激光器的光谱特性，消除了对工作范围和空间分辨率的传统限制。在实验中，测量了3.7公里的距离，分辨率为9.4毫米。
We report an application of the frequency-shifted feedback (FSF) laser to optical ranging. The FSF laser output consists of periodically generated chirped frequency components whose chirp rate is faster than 100 PHz/s (P=10/sup 15/). By taking advantage of the spectral features of the FSF laser, the conventional limits on operating range and spatial resolution are removed. In the experiment, a distance of 3.7 km was measured with a resolution of 9.4 mm.
