Airborne laser remote sensing is extensively used in geophysical explorations. Laser-remote-sensing studies are often undertaken to predict the availability of mineral resources in a target area. A major issue encountered in such studies concerns the acquisition of the ground-vibration information and analysis of the optoelectric characteristics of the corresponding target vibration. Our paper presents a scheme involving the use of a laser remote sensing system (LRSS) to realize the geophone-detection function and experimentally verify the optoelectric characteristics of the target ground vibration. As observed, the proposed LRSS demonstrates a 19- to 98-V s / cm sensitivity range for the low- to medium-frequency vibrations in the 0- to 600-Hz range. Overall, the LRSS could sense a wide range (0 to 4 kHz) of ground-vibration frequencies. Our research is expected to open avenues for electro-optical sensing technologies to be used in applications such as hidden-structure detection and non-line-of-sight imaging.

用于测量地面振动的激光遥感的光电特性

机载激光遥感广泛用于地球物理勘探中。经常进行激光遥感研究来预测目标地区矿产资源的可用性。在此类研究中遇到的主要问题涉及地面振动信息的获取以及相应目标振动的光电特性分析。我们的论文提出了一种方案，该方案涉及使用激光遥感系统（LRSS）来实现地震检波器检测功能，并通过实验验证目标地面振动的光电特性。如所观察到的，拟议的LRSS对0至600 Hz范围内的中低频振动表现出19至98 V s / cm的灵敏度范围。总体而言，LRSS可以感知大范围（0至4 kHz）的地面振动频率。
