binocular vision
雙眼視覺;雙目鏡觀察
Binoculars(雙筒望遠鏡)是一種利用雙目視覺原理設計的便攜式光學儀器,主要用于遠距離物體的觀測和細節放大。其核心結構由兩組平行排列的望遠鏡組成,通過棱鏡系統(常見類型包括屋脊棱鏡和普羅棱鏡)矯正圖像方向,使觀測者雙眼同時獲得立體影像,提升觀測的舒適性和空間感知能力。
放大倍數與物鏡直徑
型號标注(如“8×42”)中,“8”表示放大倍數,“42”代表物鏡直徑(毫米)。放大倍數越高,視野越窄;物鏡直徑越大,進光量越多,適合低光環境觀測。

應用場景
現代雙筒望遠鏡融合相位校正鍍膜和ED玻璃技術,顯著減少色差并提升成像銳度。部分高端型號支持激光測距和圖像穩定功能(來源:光學工程期刊)。
Binoculars 是英語中常用的名詞,指雙筒望遠鏡,其核心含義與用法如下:
