通过把光强度的变化转换成电信号的变化来实现控制的。
P+F光电传感器在一般情况下，有三部分构成，它们分为：发送器、接收器和检测电路。
发送器对准目标发射光束，发射的光束一般来源于半导体光源，发光二极管（LED）、激光二极管及红外发射二极管。光束不间断地发射，或者改变脉冲宽度。接收器有光电二极管、光电三极管、光电池组成。在接收器的前面，装有光学元件如透镜和光圈等。在其后面是检测电路，它能滤出有效信号和应用该信号。
P+F光电传感器在不同所制成的光学测控系统是多种多样的,按光电元件（光学测控系统）输出量性质可分二类,即模拟式光电传感器和脉冲（开关）式光电传感器.模拟式光电传感器是将被测量转换  光电传感器
成连续变化的光电流,它与被测量间呈单值关系.模拟式光电传感器按被测量（检测目标物体）方法可分为透射（吸收）式,漫反射式,遮光式（光束阻档）三大类.所谓透射式是指被测物体放在光路中,恒光源发出的光能量穿过被测物,部份被吸收后,透射光投射到光电元件上;所谓漫反射式是指恒光源发出的光投射到被测物上,再从被测物体表面反射后投射到光电元件上;所谓遮光式是指当光源发出的光通量经被测物光遮其中一部份,使投射到光电元件上的光通量改变,改变的程度与被测物体在光路位置有关.
