The purpose of this article is in order to design a kind of steady, high-efficient and low noise single-photon detector system based on the character of commercially available avalanche photodiodes (APD), and do some previous technical research.

• 本论文的目的是基于商售雪崩光电二极管(APD,Avalanche Photodiodes)的特点,为设计出一种稳定、高效和低噪声单光子探测器系统做前期技术研究。
