摘要

無論是基於對海洋及內陸水域經營管理或資源運用的需求，或是航行導航的需要，測深是探測水域之基本工作。從手持測量工具直到探測儀器問世，水深探測的方法與時漸進，如聲納利用聲波在水中傳導能量，測深光達則利用綠光雷射穿透水體。過去海洋測繪多利用船隻配合聲納做為主要測深工具，近期空載雷射掃瞄應用於近岸測繪，使得水深探測的範圍得以不受載具作業安全性之限制，而可以測繪近岸的淺水及多礁區域。本文主要探討比較聲納及測深光達兩種不同的測深方法之原理及作業方式。

Navigation requirement speeds up people's activity to ocean exploration, from manual lead line survey to echo sounding, methods of sounding improving with time. Such as sonar transport energy by sound wave and airborne bathymetric LiDAR uses doubled frequency green laser to penetrate water. In the past, bathymetric chart can be surveyed by means of echo sounder; laser scanning applications in shallow water expands the coverage of depth measurement without limitation of operational safety. In this article, shipborne sonar and airborne bathymetric LiDAR is investigated and their theory and operation method are introduced.
