摘要
介绍采用光纤传输方式实现两路1000f/s高帧频CCD的数字化信号远距离传输,阐述了系统的原理及硬软件实现方法。目前实现了15km以上的远距离传输和计算机实时显示。整个系统主要包括了数字信号复用、光发射、光接收、解复用以及PCI数据传输卡等部分。
In this paper, we adopt fiber-optic transmission for overcoming the difficulty of long-distance transmission of two channels of 1 000 frames/s CCD signals. We describe in detail the system principle and the implementation of hardware and software. Currently the transmission at a distance of 15 km and real-time computer display has been realized. The whole system is maily composed of digital signal multiplexer, demultiplexer and PCI data-sampling card.
