Intensity dataset acquired through laser scanning of lunar and Martian soil simulants

The data were acquired using two different types of terrestrial laser scanners. The first was a time-of-flight scanner Leica ScanStation C−10, the second was a phase-shift scanner Z + F IMAGER 5016.
The research programme covered scanning soil specimens from different distances (15 m, 30 m, 60 m, 90 m, 120 m, 150 m, 200 m). Lunar Soil Simulant (LSS), Martian Soil Simulant (MSS) and Earth Soil Simulant (ESS) were used to prepare target specimens for scanning. The target specimens were oriented approximately perpendicular to the laser beam. The incidence angle was ranging between 0 and 1.5degree.

本数据集采用两款不同类型的地面激光扫描仪（terrestrial laser scanner）采集获取。第一款为飞行时间扫描仪（time-of-flight scanner）Leica ScanStation C−10，第二款为相移扫描仪（phase-shift scanner）Z + F IMAGER 5016。

本研究方案涵盖了不同扫描距离下的土壤样本扫描作业，扫描距离分别为15 m、30 m、60 m、90 m、120 m、150 m及200 m。实验采用月壤模拟物（Lunar Soil Simulant, LSS）、火星土壤模拟物（Martian Soil Simulant, MSS）与地球土壤模拟物（Earth Soil Simulant, ESS）制备扫描目标样本。目标样本的摆放姿态大致垂直于激光光束，入射角介于0°至1.5°之间。
