1
该光电二极管安放在一个电屏蔽的暗箱中。
The photodiode is placed in an electrically shielded dark box.
2
该通信系统还受背景光、雪崩光电二极管（APD）增益和调制消光比等因素的影响。
The results also show that the performance of this communication system can be affected by background optical, APD gain and modulation extinction ratio.
3
考虑了工作信号躁声，感光光电二极管深嵌入硅片中，与芯片表面上产生噪声的元件相隔离。
Operating signal noise was also considered, and the sensor photodiodes were deeply embedded in silicon to isolate them from noise-causing elements on the chip surface.

光电二极管
光电二极管（Photo-Diode）和普通二极管一样，也是由一个PN结组成的半导体器件，也具有单方向导电特性。但在电路中它不是作整流元件，而是把光信号转换成电信号的光电传感器件。
