据“国际舰队”杂志一九七八年五、六月号报道。奥地利Graz AVL公司弹道部已发展成一种控制先进榴弹质量並检测共外弹道的测量仪器450型激光屏。该系统现已与框架、调整反射鏡和反射器以及410型测量及数据处理装置一起使用。测量头內有光发射器和接收器。用固定在距测量头1500毫米处的Scotchlite塑料胶片做反射器。平行的氦氖激光束经反射鏡两次偏转,使测量仪体积紧凑。在光络扩展裝置小,光束在一平面上扩展成一发散图样。测量头前透鏡中有附加偏转,使光束构成为一200毫米的平行光带。借助光学扩展装置中相位格柵和柱透鏡的结合使图样更光亮。
According to “International Fleet” magazine reported in May and June 1978. The ballistic division of the Graz AVL company in Austria has evolved into a 450-type laser screen measuring instrument that controls the quality of advanced grenades and detects a common external trajectory. The system is now used with frames, alignment mirrors and reflectors, and Model 410 measurement and data processing equipment. Inside the measuring head there are light emitters and receivers. Reflectors are made of Scotchlite plastic film, which is fixed at 1500 mm from the measuring head. The parallel helium-neon laser beam is deflected twice by the mirror to make the measuring instrument compact. In the optical network expansion device is small, the light beam in a plane expanded into a divergent pattern. There is an additional deflection in the front lens of the measuring head to make the beam a parallel light band of 200 mm. The pattern is made brighter by the combination of the phase grid and the cylindrical lens in the optical expansion device.
