潛望鏡維基百科,自由的 encyclopedia 潛望鏡(Periscope),是一種利用光線反射原理所製作的光學儀器,最常被用在潛水艇用以在水下觀察水面上的動靜。曾在塹壕戰中被用來從壕溝觀察敵軍動態。潛望鏡並非只有軍事用途,過往雙層巴士亦有裝置潛望鏡,讓坐在下層的司機可觀察上層的情況,雙層巴士的潛望鏡至2000年代才逐漸由閉路電視取代[1]。 Military handheld periscope optical design. 1 - Eyepiece 2 - Diagonal prism 3 - Handle 4 - 6 - Erecting lenses 5 - Periscope tube 7 - Field lens 8 - Lens 9 - Head diagonal prism 10 - Window 潛望鏡示意圖 Principle of the periscope.
