We constructed a laser scanning terahertz (THz) imaging system for high-speed imaging by using a galvano scanner and an organic nonlinear optical crystal, DASC, as a two-dimensional THz emitter. Using this system, we succeeded in obtaining high-resolution THz images of a test sample.
We have demonstrated a terahertz (THz) detector system which employs three terahertz photoconductive semiconductor detectors to realize a response to a wide frequency range of 0.8 to 4 THz and a mechanical 4 K GM refrigerator instead of a liquid helium container to perform practical and convenient use. Optical and electrical performance of the THz detector system was evaluated at an operation temperature...
We have fabricated a generation and detection system of photomixing signals using a photomixing technique and a Josephson junction detector. Up to now, an electromagnetic wave generated by a heterodyne mixing of two lasers was emitted from an antenna, and irradiated to a Josephson junction. In this study, we have developed the system, and the photomixing signal was introduced into a coaxial cable...
