20.500.12556/RUL-130312 Spectroscopic terahertz imaging at room temperature employing microbolometer terahertz sensors and its application to the study of carcinoma tissues A terahertz (THz) imaging system based on narrow band microbolometer sensors (NBMS) and a novel diffractive lens was developed for spectroscopic microscopy applications. The frequency response characteristics of the THz antenna-coupled NBMS were determined employing Fourier transform spectroscopy. The NBMS was found to be a very sensitive frequency selective sensor which was used to develop a compact all-electronic system for multispectral THz measurements. This system was successfully applied for principal components analysis of optically opaque packed samples. A thin diffractive lens with a numerical aperture of 0.62 was proposed for the reduction of system dimensions. The THz imaging system enhanced with novel optics was used to image for the first time non-neoplastic and neoplastic human colon tissues with close to wavelength-limited spatial resolution at 584 GHz frequency. The results demonstrated the new potential of compact RT THz imaging systems in the fields of spectroscopic analysis of materials and medical diagnostics. compact THz sensors and components THz imaging systems multispectral THz imaging medical THz imaging kompaktni THz senzorji in komponente THz slikovni sistemi multispektralne THz slike medicinske THz slike true false true Angleški jezik Slovenski jezik Članek v reviji 2021-09-13 13:54:37 2021-09-13 13:54:38 2022-09-09 04:15:50 0000-00-00 00:00:00 2016 0 0 15 str. iss. 4, art. 432 Vol. 16 Apr. 2016 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 621.3.029.6 1424-8220 10.3390/s16040432 11319124 RAZ_Kasalynas_Irmantas_2016.pdf RAZ_Kasalynas_Irmantas_2016.pdf 1 354667B0D1C2248E0BCB26D68B7325B4 cbac8450f83e9877ab5801afbe554b75cb47fa7ff4f42710671af8d1380ceed0 fa78f98a-1489-11ec-a523-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=147395 http://www.mdpi.com/1424-8220/16/4/432 1 1ed573e8-1489-11ec-a523-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=147394 Fakulteta za elektrotehniko 0 0 0
