澳大利亚对海洋深度的遥感有特别的兴趣,因为它有近300万平方公里的大陆架未被适当地绘进海图。在这种情况下,澳大利亚皇家海军的水文学家最近发起了机载激光深度探测器的研制。深度测量的原理是基于测量短激光脉冲从海洋表面和从海底先后两次反射的时间间隔。Nd:YAG倍频激光器的红外输出用于遥感海洋表面,绿色输 Australia has a special interest in remote sensing of oceans as it has nearly 3 million square kilometers of continental shelf not properly charted. Under such circumstances, hydrological experts from the Royal Australian Navy recently launched the development of an airborne laser depth detector. The principle of depth measurement is based on measuring the time interval after which a short laser pulse is reflected twice from the ocean surface and from the sea floor. The infrared output of the Nd: YAG frequency doubling laser is used to remotely sense the surface of the ocean and the green color
