摘　　要：基于APD阵列的探测系统非常适合超高灵敏度、超高速探测,在主被动成像、激光雷达、医学检测、波前探测、光纤通信等领域应用广泛,时间数字转换器(Timeto Digital Converter,TDC)是其中的核心电路,完成对光子飞行时间(Time of Flight,ToF)的高精度量化,对TDC电路的研究具有非常重要的军事和民用价值。本文首先介绍了TDC电路的原理与最简单的直接计数型结构,然后按三种典型结构分别综述了国内外适用于APD阵列的TDC电路的发展历程和最新成果,其中主要介绍了相位插值型TDC,最后比较了三种典型结构的特点,并总结了未来研究趋势。The detection system based on Avalanche Photodiode(APD)arrays is highly suited for ultra-high sensitivity and ultra-high speed applications,and is widely used in active and passive imaging,LiDAR,medical detection,wave-front detection,optical fiber communication and other fields.The time to Digital Converter(TDC)is one of the core circuits,which completes the Time of Flight(ToF)quantification of the photons with high accuracy.In this paper,the principle of TDC circuit and the simplest direct counting structure are introduced at first,and then the development history and latest achievements of domestic and international TDC circuits applicable to APD arrays are viewed ac-cording to the three typical structures,of which the phase-interpolated TDCs are mainly introduced.Finally,the char-acteristics of three typical structures are compared,and the future research trends are summarized.
