Recently, we have succeeded in the development of high power and high sensitivity THz wave spectral imaging system using injection-seeded THz parametric generation and detection. A dynamic range of 100 dB has been obtained, which is much higher than that of our report in 2003. In this study, the spectral imaging system that we built using injection-seeded THz parametric generation and detection can successfully identify reagents through thicker material than the previously used thin envelopes.
