四象限雪崩探测器的角分辨力直接影响跟踪系统的跟踪精度。
The tracking precision of laser tracking system is affected by the angular resolution of quadrant avalanche photodiode.
因此很多这类微型通信设备可能仅需一节小型的五号电池（AA型，电压1.5伏）就可以工作，而传统的雪崩光电探测器需要20-30伏的电量供应。
Thus many of these tiny communication devices could potentially be powered by just a small AA-size battery, while traditional avalanche photodetectors require 20-30V power supplies.
这种微小的型号也意味着，与常规的雪崩光电探测器相比倍增的噪声减弱了50%至70%。
The tiny size also means that multiplication noise is suppressed by 50% - 70% with respect to conventional avalanche photodetectors.
