摘要
由于红外线以光的速度在空气中传播 ,因此不能像超声波那样简单地靠测量发送信号与接收信号的时间差来计算距离。基于叠加的思想提出了一种利用红外线测量距离的方法 ,并给出了具体的实现方案。
Because the infrared rays spreads in the air in the speed of light, the distance can′t be got simply by measuring the time between sending and receiving like ultrasonic Basing the idea of piling up, a kind of distance measurement method using infrared rays is introduced, at the same time, the specific realizing scheme is provided
