Abstract :
We developed compact terahertz time-domain spectroscopy (THz-TDS) head and system-scanning imaging stage for large area inspection of post matters. In order to focus the THz waves, we mounted either four parabolic reflectors or two silicon hyper-hemispherical lenses on the mobile imaging stages, and compared the spatial resolutions of the stages together with the measurable THz bandwidths.
