相位调制器与振幅调制器是连续变量量子密钥分发中不可缺少的光调制器件。本文以量子安全通信系统的硬件为平台，设计了LiNbO3相位调制器的驱动电路，性能测试电路，同时给出了振幅调制器的性能监控电路。从理论与实验上对方案的可行性与可靠性进行了验证。

Phase modulator and amplitude modulator are both indispensable optical modulator in quantum cryptographic communication. In this paper, we proposes a design of drive module and a performance monitoring system for LiNbO3 phase modulator and amplitude modulator by employing the hardware of a quantum security communication system. The feasibility and reliability of the scheme are verified through the experimental result and theoretical analysis.
