看过电影《魔鬼终结者》的朋友大概都记得其中一个镜头:终结者敲开莎拉的房门,在问过其姓名后,举起了手枪——一个小红点出现在莎拉惊恐的脸上,然后是一声枪响。在随后的情节,以及其它许多影视作品中,这类镜头也经常出现:一个小小的红点引来一发致命的子弹。这个红点就来自于特种部队(也包括一些杀手)经常使用的激光瞄准具(图1)。 One of them was probably remembered by friends who watched the film “The Terminator”: The Terminator knocked on Sarah's door and asked for his name, raising his pistol - a little red dot appeared in Sara's horror Face, then a gunshot. In subsequent episodes, as well as in many other film and television productions, such shots also appear frequently: a tiny red dot leads to a deadly bullet. This red dot comes from the regular use of laser sights by Special Forces (including some killers) (Figure 1).
