Reconfigurable terahertz spatial differentiation via incident angle tuned beam shifts on a Bi2Te3 platform

Optical spatial differentiation offers an ultrafast, low-power route to edge detection by directly processing the optical field and can address the inherent diffraction-limited blurring of terahertz (THz) imaging. However, existing THz edge detection schemes face persistent bottlenecks. Metasurfaces and diffractive dev...
