d.o.o, Sempeter pri Gorici, Slovenija KW nema KR nema The THz radiation brings new technology challenges and new opportunities to overcome some of the current application obstacles. In the paper a portable THz system is presented operating at room temperature. The presented solution is robust and inexpensive, convenient for many applications. The THz sensor fabricated at the Faculty of Electrical Engineering in the Laboratory for Microelectronics is currently one of the best sensors in its frequency operating range. It reaches sensitivity up to 1000V/W and NEP down to 5pW/?Hz in vacuum. With the proposed system solution variety of application can be covered. Some imaging results captured with the proposed system at different stand-off distances are shown in the paper.

Performance enhancement of a very inexpensive millimeter-wave (MMW)/terahertz (THz) sensor for MMW/THz imaging systems is experimentally demonstrated in this study. The MMW sensor is composed of a glow discharge detector (GDD) and a light-to-frequency (LTF) converter combination. The experimental results given in this study show an improvement in the performance parameters of the detector element, such as the minimum detectable signal, as well as the signal to noise ratio (SNR) and the noise equivalent power (NEP), when a NIR long-pass filter was inserted between the GDD and the LTF combination. A detailed derivation of the NEP of this unique sensor is presented in this work. Based on this derivation and the experimental measurements, the NEP value was calculated.
