提出了一种太赫兹时域反射光谱(THz-TDRS)中错位相位误差校正的数值方法。所开发的算法是基于最大熵原理,可以很容易地实现到数据处理,允许一个揭示材料参数的不透明材料从太赫兹反射测量。该方法解决了太赫兹中继卫星的相位恢复问题,大大简化了实验过程。(C)2004年,美国物理学会。
We propose a numerical method for the misplacement phase error correction in terahertz time-domain reflection spectroscopy (THz-TDRS). The developed algorithm is based on the maximum entropy principle and can be readily implemented into data processing, allowing one to reveal material parameters of the opaque materials from the THz reflection measurements. The method resolves the phase retrieval problem in the THz-TDRS and dramatically simplifies the experimental procedure. (C) 2004 American Institute of Physics.
