摘要
介绍了一种软件计算远红外激光干涉仪相位差的方法。对比了软件程序与硬件相位计在HT-7实验中的处理结果,总结了软件处理所得相位差的特征,并在此基础上求出了真实的等离子体密度。最后,对实验结果进行了细节分析、误差分析,对软件处理时间进行了分析,得出软件方法可以获得更好的时间分辨率且具有进行实时处理的可行性。
A software method for computing the phase difference of FIR interferometer was presented in this article. Compared the experimental results processed by software program and the one processed by hardware phasemeter in the HT- 7 tokamak,and summarized the characteristics of the phase difference calculated by software, and then derived the true plasma density. In the end, done the detail analysis and error analysis of the experimental results and analyzed the processed time of software program, and concluded that software method has a better temporal resolution, has the feasibility of real time processing.
