photosensitive diode

基本解释

The diode is photosensitive, so it should be enclosed with R1 in a light-tight electrostatic shield.
该二极管是感光性的，因此应与R1一起被安装在一个不透光的静电屏蔽套内。
When the web worked normally, it passed through the central axle of the light pole so that the optical power received by photosensitive diode was normal constant.
带材正常运动时处于光柱的中心位置，光电二极管接收到的光功率为一定值；
On the basis of accurate theory, using laser emitter and photosensitive diode as testing sensor, a set of laser equipment for automobile axle depth of parallelism test is designed and produced.
利用激光发射器和光敏接收器作为检测传感器，基于准确的检测理论，设计出了激光检测法检测汽车前、后轴平行度的检测装置。
