介绍了光电模拟器的设计与实现以及在半实物仿真试验中的应用.在硬件设计上，设备采用工控机平台，以生成考核被试系统光电设备所需要的模拟视频图像为目的，进行设计和实现.在软件设计上采用Visual C＋＋编程环境实施软件设计与开发，完成模拟航路的生成、模拟视频图像的发送和试验数据的处理评估等功能.

The design and realization of electro-optical simulation as well as its application in semi-physical emulation test were introduced. In the hardware design, the hardware of electro-optical simulation is based on the industry-control-computer platform. The hardware was designed and realized in order to provide the video simulation image for the tested equipment. In the software design, the electro-optical simulation software was written in Visual C++ programming environment, which supports the functions such as emulated trace creation, video simulation image sending, test data process and evaluation.
