Terahertz sensors

Many possible uses of terahertz sensing and imaging are proposed in manufacturing, quality control, and process monitoring. These in general exploit the traits of plastics and cardboard being transparent to terahertz radiation, making it possible to inspect packaged goods. The first imaging system based on optoelectronic . The Terahertz Sensors and Systems Group (THZ) applies its telecom matured InP-technology for developing photomixers and photoconductive antennas which convert optical signals in the 1. The THz range in the electromagnetic spectrum (Fig.1) is extending from 2GHz ( meV) to THz (meV).

A lot of attractive applications in security, medicine, biology, science and non-destructive materials testing have been demonstrated already.

Terahertz sensors are used to generate and detect electromagnetic waves at the terahertz frequencies for spectroscopy, sensing, and imaging applications. The recent advance in IR and Terahertz optical sources and detectors has opened up new opportunities for sensing and imaging techniques and applications. This Special Issue of Sensors, entitled “IR and THz sensing and imaging”, will focus on all aspects of the research and development related to these areas.

The Terahertz Sensing group focuses on research and education in the fields of applied electromagnetics, antennas, optics and sensor systems for space. Due to the formation of Fabry-Perot resonance of the spoof surface plasmons mode on the corrugated metal stripe, the extremely sharp . A new type of sensor , that is much faster than competing technologies used to detect and identify hidden objects, has been developed by scientists at the University of Warwick.

In this paper we report on the design, fabrication and characterization of terahertz ( THz ) bi-material sensors with metamaterial absorbers.

MEMS fabrication-friendly SiOx and Al are used to maximize the bimetallic effect and metamaterial absorption at 3. Abstract: We discuss the design considerations of traveling-wave electrooptic terahertz sensors , wherein we analyze limitations in frequency response due to velocity-mismatch in the sensor crystal. In zincblende electrooptic materials, optical group velocities are found to be able to match the phase velocity of low frequency . The frequency response characteristics of the THz antenna-coupled NBMS were determined employing Fourier transform . Thermo-graphic cameras (for night vision). The Terahertz ( THz ) region of the electromagnetic spectrum commonly includes all the frequencies between 1GHz (mm) and THz (μm) as shown on figure 1.
