False color picture of the watermark of a €20 bank note, showing the amplitude of the transmitted terahertz electrical field signal with varying optical parameters of the material; the highest amplitude is shown in red, and the lowest in blue. The image was recorded by Menlo Systems’ TERA K15 THz-TDS system with TERA Image imaging extension unit and ImageLab processing software.
Terahertz time-domain spectroscopy has undergone a quiet evolution and is now moving from research labs onto production lines.
