阐述一套机载运行的光学－机械扫描式激光测距和被动式热红外外扫描成像组合遥感器，结合飞机平台的姿态测量和GPS定位，可实时（准实时）获取地面景物的三维位置和影像灰度信息。由多源数据采集技术获得的多种同步数据经地面计算机回放和处理，可以快速生成数字地面高程模型（DEM）和地学编码图像。扫描激光测距仪与扫描成像仪的电同步技术控制激光测距采样时刻与图像采样时刻在时序上的一致性，从而达到高程数据与图像像元的匹配。

The Airborne Scanning Laser Ranging-Imager Sensor (ASLRIS) is a new generation of remote sensing and mapping system for providing 3D geosciences information. The system integrates the laser altimeter, IR imager, Differential Global Positioning System (DGPS) and Inertial Navigation System (INS), by which Digital Elevation Model (DEM) and Georeferenced Image (GI) can be generated quickly and effectively without ground control points. The electric synchronization technology makes sampling-time in consistency with laser ranger and scanning imager to match height data and image data.
