The noise performance of photodiodes can be very good. For high photocurrents, it can be limited by shot noise, although thermal noise in the electronics is often stronger than that. For the detection of very low light levels (e.g. for photon counting), the dark current can also play a ...
光电二极管可以在两种模式下工作：光伏模式和光电导模式。在光伏模式下，它类似于太阳能电池，用于测量受光辐照的光电二极管产生的电压。但需注意，电压与光功率之间的关系呈非线性，且动态范围较小，无法达到峰值速度。相比之下，光电导模式更为常用。在此模式下，二极管上施加反向电压（即，在无入射光时二极管不导电...
