Spinning meta-optics for spectro-polarimetric thermal imaging?

The article focuses on improving thermal imaging through heat-assisted detection and ranging (HADAR), developed by Professor Zubin Jacob's group at Purdue University, which enhances texture details and enables machine perception in darkness. It reports that recent advancements in meta-optics have led to a metasurface-based approach for spectro-polarimetric thermal imaging, allowing for compact and effective capture of spectral and polarization details.
