Terahertz Systems
-
Terahertz waves are electromagnetic waves in the frequency band between radio waves and light waves. It combines the transmissivity of radio waves and the straightness of light waves and provides fingerprint spectra based on intermolecular interactions from small molecules to high polymers. By utilizing of this characteristic for spectroscopic and imaging measurements, it is possible to apply them to nondestructive analysis that has never been done before.

Pyroelectric Detectors
-
Pyroelectric detectors are thermal detectors; i.e. they create an electric signal due to temperature changes in the chip. This temperature change is caused by absorption of light. We do use LiTaO3 and DLaTGS as pyroelectric materials. Basically such detectors cover the whole spectra. However, they are mainly used for mid-wave and long-wave infrared detection (MWIR and LWIR). In addition, the usage in the THz region seems to become more popular these days.
