摘　　要：介绍了10.6μm波段扫描负折射功率的实时探测系统,在实验上为探测光子晶体光频波段负折射现象提供了实验平台。该系统通过数据采集卡实现计算机对旋转台及平移台的控制,在以光子晶体样品为探测中心的轨道上,对折射光的整个空间功率分布进行实时采集和绘图。这一实验系统能够精确便捷地实现负折射现象在光频波段的探测。根据折射光最大光功率出现的位置,测得光束通过光子晶体样品的负折射现象,而且与理论结果基本吻合。A real-time detection system in 10.6 μm wavelength is introduced which is applied to experimental verification of negative refractive phenomena in photonic crystal at optical frequencies. The system is controlled by computer and it can move ac- curately and perform real-time sampling and drawing of the power of the refractive light automatically. The experimental system is credible and accurate. And the results of the experiment conform to the simulation result.
