英国逊·EMI电子设备有限公司目前已经开始试飞一种新型电子设备。它能向直升飞机驾驶员预报飞行路线上的障碍物。该设备采用激光测距技术搜索直升飞机下方的地域。在处理完反射回来的信号后,它能用所提供的高精度距离和方位信息组成激光图。该设备安装在直升飞机的机头下面。当设备通过方位平面时,反射镜使1R激光器中窄波束以垂直平面旋转,每秒钟搜索一次飞机下方的整个区域。利用信号处理与飞机飞行路线和高度有关的信息设备就可以音频和视频形式,或者以地形图 The British EMI · Electronic Equipment Co., Ltd. has now started a new test flight electronic equipment. It can predict to the helicopter pilot obstacles on the flight path. The device uses laser ranging technology to search the area under the helicopter. After processing the reflected signal, it can compose the laser map with the provided high-precision range and bearing information. The device is installed under the nose of the helicopter. As the device passes through the azimuth plane, the mirror rotates the narrow beam in the 1R laser in a vertical plane, searching every second for the entire area under the aircraft. The use of signal processing equipment and aircraft flight routes and height-related information equipment can be audio and video, or topographic map
