激光测高技术的发展趋势

激光测高技术作为一种的先进测量手段，已广泛应用于地形地貌测绘、地球科学研究、航天工程、城市规划、森林资源调查等诸多方面。虽然激光测高技术已相对成熟，但随着激光技术的发展和应用需求的拓展，激光测高技术仍有很大的发展空间。通过对国外近期研制或正在研究的几个具体激光测高设备的介绍和分析，总结了激光测高技术的一些典型技术特点和发展趋势，介绍了多光束发射和接收、单光子探测、多回波测量和多功能集成等技术在激光测高仪的应用。这对开展新型激光测高技术的研究具有一定参考价值。

Progress and prospect of laser altimeter technology

Study on laser altimeter technology has had a history of decades.It has also been used in wide application fields such as topography,geodesy,astronautics,resource survey,etc.Although the technology is relatively mature,it still has a wide developing space as the laser technology and application requirements develop fast.By studying several practical systems which are developed recently or under research,the developing tendency and prospect of laser altimeter are summarized.The technology of multi-beam,single photon detection,multi-shot counting and multi-function system are introduced,which might offer reference for the research of new type laser altimeter.
