摘要:

双梳状激光雷达具有高速执行高分辨率测距的潜力。在这里,通过涉及电光调制器和外差检测的实现,我们量化的测距系统之间的权衡精度和非模糊范围(NAR)使用一个独特的性能因素。我们突出的梳振幅包络的影响,精度与距离测量的光梳的重复率的限制。的影响的梳重复率的NAR和精度上的说明,通过一个设置,允许距离测量与可调NAR。最后,我们证明了解决不同目标的不可能性,量化对测量距离的影响,并在干扰的非线性效应使测量不可能的条件下发展。

英文摘要:

Dual-comb LiDARs have the potential to perform high-resolution ranging at high speed. Here, through an implementation involving electro-optic modulators and heterodyne detection, we quantify the ranging systems trade-off between precision and non-ambiguity range (NAR) using a unique performance factor. We highlight the influence of the comb amplitude envelope on the precision with a distance measurement limited by the repetition rate of the optical comb. The influence of the combs repetition rate on the NAR and on the precision is illustrated through a setup allowing distance measurement with a tunable NAR. Finally, we demonstrate the impossibility to resolve different targets, quantify the impact on the measured distance and develop on the conditions in which non-linear effects of the interference make the measurement impossible.
