澳大利亚Tasmania大学的研究人员研制出一台激光系统,它能自动测定并保持海上船只与岸上固定点的相对位置。这对于航海工作人员在从事象打桩、打捞和疏竣这类普通港口作业时确定并保持船只固定位置特别重要。这种船载仪器叫做激光角扫描器,它用微机计算,并不断地把坐标信息提供给船只的导航系统。该系统可以代替两三个船员手工控制测量仪器。 Researchers at Tasmania University in Australia have developed a laser system that automatically measures and maintains the relative position of a marine vessel to a fixed point on the shore. This is particularly important for navigational staff to identify and maintain the fixed positions of ships when operating in ordinary ports such as piling, salvage and dredging. This shipborne instrument is called a laser angle scanner, which uses computer calculations and constantly provides coordinate information to the vessel's navigation system. The system can replace two or three crew manual control of measuring instruments.
