摘要

近年来,激光雷达在环境遥感方面的应用不断扩大和深入。其中,连续波(CW)距离分辨(RR) S-lidar (S来自Scheimpflug)已被证明是一类新的、有前途的非接触、无扰动激光传感器。他们使用低功率连续波二极管激光器,一种非常规的景深扩展技术和纳米光子技术的最新进展来实现紧凑和具有成本效益的遥感器。本文的目的是提出一种通用的方法来证明一组非能量s激光雷达参数的选择适用于广泛的应用和距离尺度,从台式试验台到10公里的路径。通过调节光模块来设置所需的工作范围的远近边界,说明了如何正确选择透镜平面和像面倾斜角度,以及焦距、激光雷达基座等。为了对S-lidar参数之间的特征关系进行广义分析,我们引入了适用于不同距离尺度的无量纲因子和准则,包括S-lidar特有的放大因子、角函数、动态范围、“一个半”条件、距离域质量因子等。它可以展示如何合理地选择命名的和依赖的非能量参数,使它们适应特定的应用。最后,我们通过演示如何在宽动态范围和高范围分辨率要求之间实现妥协,转向合成任务。所进行的分析和综合的结果可以提高设计解决方案的有效性,从而进一步促进s -lidar用于环境遥感,并更好地适应广泛的特定应用和范围尺度。

Designing CW Range-Resolved Environmental S-Lidars for Various Range Scales: From a Tabletop Test Bench to a 10 km Path
In recent years, the applications of lidars for remote sensing of the environment have been expanding and deepening. Among them, continuous-wave (CW) range-resolved (RR) S-lidars (S comes from Scheimpflug) have proven to be a new and promising class of non-contact and non-perturbing laser sensors. They use low-power CW diode lasers, an unconventional depth-of-field extension technique and the latest advances in nanophotonic technologies to realize compact and cost-effective remote sensors. The purpose of this paper is to propose a generalized methodology to justify the selection of a set of non-energetic S-lidar parameters for a wide range of applications and distance scales, from a bench-top test bed to a 10-km path. To set the desired far and near borders of operating range by adjusting the optical transceiver, it was shown how to properly select the lens plane and image plane tilt angles, as well as the focal length, the lidar base, etc. For a generalized analysis of characteristic relations between S-lidar parameters, we introduced several dimensionless factors and criteria applicable to different range scales, including an S-lidar-specific magnification factor, angular function, dynamic range, “one and a half” condition, range-domain quality factor, etc. It made possible to show how to reasonably select named and dependent non-energetic parameters, adapting them to specific applications. Finally, we turned to the synthesis task by demonstrating ways to achieve a compromise between a wide dynamic range and high range resolution requirements. The results of the conducted analysis and synthesis allow increasing the validity of design solutions for further promotion of S-lidars for environmental remote sensing and their better adaptation to a broad spectrum of specific applications and range scales.
