美国空军的第一架激光跟踪器,是由地面试验设备Sylvania的电子系统小组研制出来的,它帮助在Wright-Patterson机场的工程师鉴定在T-39飞机上试验的飞机离地位置测量系统,作为一种精密测量工具,正在证明是有价值的。 为精密的进场区跟踪系统设计的PAATS跟踪器,采用一台在1.06微米波长工作的Nd:YAG激光器,激光器重复频率为每秒100次,输出能量为50毫焦耳。此跟踪器能够精确确定飞机的位置,在飞行位置达32公里的距离下,精度在1.5米以内。 这个系统装配在一辆有蓬车里,以便于 The first US Air Force laser tracker, developed by the Electronic Systems Group at Ground Testing Equipment Sylvania, helps engineers at Wright-Patterson Airport identify aircraft ground-position measurement systems tested on T-39 aircraft as A precision measurement tool is proving to be valuable. The PAATS tracker for a precision approach area tracking system uses a Nd: YAG laser operating at a 1.06 micron wavelength with a laser repetition rate of 100 times per second and an output energy of 50 millijoules. This tracker accurately pinpointed the position of the aircraft within a distance of up to 32 km at flight position with an accuracy of less than 1.5 m. The system is assembled in a caravan to facilitate
