Abstract

本实用新型涉及一种直角镜,其特征在于直角镜是由两个平面镜组成,镜面朝内且互相垂直的镜子。可以把两个平面镜通过简单地粘合制作而成。物体经过两次平面反射后的像是物体真实的样子,当人们使用这种镜子时就能看到自己正面真实的面目。

Description

直角镜
技术领域
光学平面镜成像
背景技术
镜子是人们日常生活中必不可少的用品之一。因为没有谁的面部长得完全对称,所以即使我们现在所使用的平面镜的平面是理想的平面,也不能反映出我们的真实长相。比如符号“←”在平面镜中就变成了“→”,符号

在平面镜中就变成了
Figure DEST_PATH_GSB00000061093200012
发明内容
直角镜是利用光的二次反射来反映出我们的真实长相。如果我们使用两个普通平面镜时,那么镜子中的镜子里的像便是我们真正的样子。当我们把两个平面镜的镜面向内垂直放置时,然后站在两镜面的夹角中,就能看到我们自己正面的真实模样。
直角镜就是一种由两个平面镜组成的镜面朝内且互相垂直的镜子。
附图说明
图1为直角镜效果图。
图2为直角镜成像原理图,其中1表示物体,2表示眼睛,3表示直角镜,4表示物体的像。
具体实施方式
按图2所示,其中1为人体本身,2为人的眼睛,当人站在直角镜的两镜面夹角内照镜子时,人体的像经过两个镜面的二次反射,直角镜里所成的人体的像就相当于将人体本身以两镜面的相交线为旋转轴转动了180度,这就相当于我们站在自己的对面看自己。
