摘要
在光电平台系统中,图像采集设备与系统之间的数字图像传输采用LVDS接口。但由于光电信号微弱、抗干扰能力差,采用传统的LVDS直流耦合传输时图像采集设备容易受到光电系统干扰,成像效果远远不如单机调试。为解决这一问题,本文设计了一种LVDS信号交流耦合传输技术,极大提高了图像采集设备的抗干扰能力。
In the optoeleetronic system, image transmission between image collection equipment and system adopts LVDS interface. When LVDS DC coupling is used to transmit data, image collection equipment is easy to be interfered by optoelectronic system, image quality is poor. To solve the problem, a LVDS AC coupling data transmission technolo- gy was proposed. Its software and hardware are introduced, and its feasibility is verified by the experiment. The results show that the anti - interference ability of image collection equipment has been greatly improved.
