摘要：

We present a high-precision time-of-flight laser radar system based on energetic (similar to 0.6 nJ) sub-ns laser pulses produced with a semiconductor laser diode. The proposed device has a single-shot precision of <5 mm at an SNR of 10 and a maximum walk error <500 ps in the dynamic range 1:250. Sub-mm precision can be achieved in ranging by means of averaging. The proposed laser radar can be used for monitoring tiny vibrations in distant targets, for example.
