Compact Thermal Imaging System Created with Spinning Metasurfaces
WASHINGTON, Jan. 15, 2024 — Researchers have developed a technology that uses meta-optical devices to perform thermal imaging. The approach provides further information about imaged objects, which could broaden the use of thermal imaging in fields such as autonomous navigation, security, thermography, medical imaging, and remote sensing. “Our method overcomes the challenges of traditional spectral thermal imagers, which are often bulky and delicate due to their reliance on large filter wheels or
