Paper Abstract

The precision of the conventional terahertz transmission measurement system with a parallel-plate sample will be reduced due to the interference effect, when the frequency of the THz source drifts. In order to solve such problem, a frequency-drift insensitive transmission measurement system composed of double-path is proposed in this paper, and an F-P interference model is built. The parameters are optimized, and the effects of the terahertz source's frequency drift on the precision of both the single- and double- path transmission measurement are analyzed and compared. The results demonstrated that such kind of measurement system could avoid the influence of the frequency-drift of the THz source, thus enhance the measurement accuracy.
