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.

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。

Just 12.2mm slim (measurement excludes lens cover), which is smaller than the thickness of a standard AA-size battery, the Cyber-shot TX55 is the world's thinnest camera in its class (among cameras with an optical anti-shake function).
