Development of terahertz-wave coherence tomography by widely tunable BW-TPO
Abstract
A Backward Terahertz (THz) Wave Parametric Oscillator (BW-TPO) is a compact THz-wave source that generates high-brightness sub-THz waves with a pulse peak of up to 200 W and a continuously tunable frequency over almost the entire sub-THz region basically. This excellent performance is useful for THz-wave coherence tomography. In particular, the transmittance is completely different depending on the material, and the high intensity output has the potential to measure even difficult-to- penetrate materials such as CFRP and GFRP. In this report, the developed swept-source THz-wave coherence tomography will be described using BW-TPO with wide 90 GHz tunability around 0.5 THz.
