In the array scheme of with the diaphragm , the optimization of semiconductor optoelectric devices array forms a sky screens . while the bullel passing through the sky screens , the outputs of optoelectronic devices are amplified and coded , and then transmitted to the computer for processing 半導體光電件陣列方案是將半導體器件陣列和光闌合理配置,形成天幕,將彈丸過靶信號光電轉換、放大,經過編碼處理,最后送入計算機處理。

According to the intersection measuring principle , two optoelectric devices intersecting with the ground into the same angle with , are placed to form one overlapping upright sky screen 交匯測量方案是利用交匯原理,放置兩臺光電檢測裝置,形成的光幕相互交疊,構成垂直于地面的交匯測量靶面。
