一种以光纤为基础的,能产生三维图象的相干激光雷达系统已经得到实验验证.外差式的光纤激光器收发信机与采用常规激光器的结构相比,系统的重量和尺寸减小了,而二极管激光器的泵浦源大大降低了功率和冷却的要求.由这种技术可能实现的柔软封装使这些仪器能安装在不能采用块状、刚性器件的地方.地面、海洋和空中监测都是光纤基激光雷达系统可以使用的场合,其中包括恶劣环境中的远程监测和安全设施中的环形监测.Coherent Technologies Inc.公司研制了这种系统,据称是在二年期间第一个这样的系统.
An optical fiber-based coherent laser radar system capable of generating three-dimensional images has been experimentally validated. The heterodyne fiber-optic transceivers, compared with conventional lasers, have reduced weight and size, Diode laser sources significantly reduce the power and cooling requirements, and the soft encapsulation possible with this technology allows these instruments to be installed where block-like, rigid devices are not amenable. Ground, sea and air monitoring are all fiber optics Based lidar systems where it is possible to use, including remote monitoring in harsh environments and ring monitoring in safety facilities, a system developed by Coherent Technologies Inc. It is said to be the first such system in two years.
