المؤلفون: Čibiraitė-Lukenskienė, Dovilė, Ikamas, Kęstutis, Lisauskas, Tautvydas, Rysiavets, Anastasia, Krozer, Viktor, Roskos, Hartmut G., Lisauskas, Alvydas
المصدر: 2020 45th International Conference on Infrared, Millimeter, and Terahertz Waves (IRMMW-THz), November 8-13, 2020, Buffalo, NY, USA . (Virtual conference)., Buffalo, NY : IEEE, 2021, p. 1-2 ; ISSN 2162-2027 ; ISBN 9781728166216 ; eISSN 2162-2035 ; eISBN 9781728166209
مصطلحات موضوعية: Temperature sensors, Sensitivity, Field effect transistors, Imaging, Lighting, Spatial resolution, Signal to noise ratio
الوصف: This work presents to our knowledge the first completely passive imaging of human body radiation below 1 THz at the room temperature without additional illumination or cooling. The successful image shows an impressive sensitivity limit of a terahertz FET detector (TeraFET). We made a 2.7 cm × 4 cm size image of a hand with the spatial resolution of 1 mm and scanning speed equal to 1 cm 2 /100 s. The SNR is only 2.5 dB and the NETD of the hand radiation at room temperature is 4.8 K.
