To meeting the applying requirement of space optical communication, we designed and realized the miniaturization of mechanical structure for electro-optic modulator.
同时为满足空间光通信使用要求，完成了电光调制器机械结构的小型化设计。

The structure of the EOS system is designed, including opto-mechanical delay line (OMDL), embodiment of electro-optic modulator, and lock-in detection module.
This paper presents a new type of Electronic Servo valve (ESV) which includes the pulse width modulator, electro-mechanical actuator and variable section area valves.
