最近国外发明了测量远方移动目标距离用的新颖的光激射器测距器,其外形类似来福枪,该装置称为柯里达(Colidar)11号的携带用测距器.白天,它能测量7哩距离以内的建筑物和目标,准确度为15呎.在理想的大气条件情况下,它能以同样的准确度测量60哩以内的目标. Recently, a novel light-launcher rangefinder for measuring the distance of moving objects in distant places has been invented which is similar in appearance to a rifle gun and is called a Colidar distance measuring device for carrying No. 11. During the day, it The ability to measure buildings and targets up to seven miles with an accuracy of 15 feet can measure targets within 60 miles with the same accuracy under ideal atmospheric conditions.
