A Telecentric Offset Reflective Imaging System (TORIS) for Terahertz Imaging and Spectroscopy
Pouyan Rezapoor, Aleksi Tamminen, Juha Ala-Laurinaho +2
Terahertz (THz) imaging has emerged as a promising technology in medical diagnostics due to its non-ionizing radiation and high sensitivity to water content. However, conventional…
