透光型光电开关的电路如图a)所示。发光器件和受光器件相对放置,中间留有间隙。当被测物体到达这个间隙时,发射光被遮住,从而使接收器件(光敏元件)能检测出物体已经到达,并发出控制信号。 反射型光电开关所发出的光经被测物体反射后再落到检测元件上,其基本情况与透光型大致相同,但由于是检测反射光,所以得到的输出电流...
At the receiver, the electric fields are detected by measuring the auto-correlation of the received light by using two-wave interferometers, which are matched to the introduced optical delays on the sensing devices. 关键词: electric field measurement lithium compounds niobium compounds electro-optical...
