Abstract
A terahertz wave is spectrally dispersed into two waves which are caused to pass through a sample liquid filmand a reference liquid filmand are then collected, and the terahertz waves in an interference state are detected by a terahertz wave detecting semiconductorConsequently, only spectroscopic information related to a distinctive characteristic of the sample liquid filmis detected. In addition, a predetermined optical path length difference is provided between a path where the terahertz wave is transmitted through the sample liquid filmand a path where the terahertz wave is transmitted through the reference liquid filmby an optical delaying unitIna frequency spectrum obtained by performing Fourier transformation over a terahertz wave signal having an interference waveform by a terahertz wave signal analyzing deviceconsequently, a feature caused by an interaction of dissimilar molecules in the sample liquid filmappears in a spectral intensity at a frequency depending on the optical path length difference.
