潜望镜维基百科,自由的 encyclopedia 潜望镜(Periscope),是一种利用光线反射原理所制作的光学仪器,最常被用在潜水艇用以在水下观察水面上的动静。曾在堑壕战中被用来从壕沟观察敌军动态。潜望镜并非只有军事用途,过往双层巴士亦有装置潜望镜,让坐在下层的司机可观察上层的情况,双层巴士的潜望镜至2000年代才逐渐由闭路电视取代[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 潜望镜示意图 Principle of the periscope.
