Abstract

The injection-seeded terahertz wave parametric generator (is-TPG) technology presented here is expected to enable measurements through thick shielding due to its wide dynamic range of over 120 dB in combination with detection methods that up-convert the terahertz wave to a near-infrared beam. Furthermore, recently machine learning has been applied to the fingerprint spectral analysis of reagents, which has enhanced identification accuracy. Real-time measurement has also been achieved by multi-wavelength generation and detection with image recognition of detection Stokes beams. We will present these improvements in is-TPG technology for non-destructive testing.
