Terahertz polarimetry detects microscopic tissue changes linked to cancer and burns

Recent advances in electronics and optics have opened new possibilities for terahertz (THz) waves--an invisible type of light that falls between infrared light and microwaves on the spectrum. The use of THz scattering for medical diagnosis is a promising frontier in this field, as THz waves can probe tissue structures in ways that traditional imaging methods cannot. Emerging THz measurement methods have the potential to detect subtle changes in tissue architecture that occur in diseases like can...
