Thz image detection
Webb11 apr. 2024 · As reported in Advanced Photonics, researchers from Fudan University’s Department of Physics recently established a novel metasurface-based approach that achieves dynamic dual-mode modulation of THz waves by varying the wavelength of pumping light with an additional knob. Webb11 apr. 2024 · One of the major applications of THz spectroscopy and imaging is in non-invasive detection of materials composition and retrieval of complex surface topography of objects in the form of 2D/3D hyper spectral images. THz-TDS imaging can be carried in transmission and reflection geometries.
