Comparing to the traditional direct phase analysis, the integration one can reflect the relation between signal and light intensity, receiving area more accurately.
同传统的相位分析法相比，积分法更能反映光电接收信号与光强、接收面积的关系。
Modulated light is used as detecting signal in this system, photodiode area array is used as receiving module, which greatly improves the sensitivity and anti-interference ability of the system.
系统采取调制光源作为探测信号，采用光敏二极管面阵作为接收组件，大大提高了系统的灵敏度和抗干扰能力。
