A New Kind of Camera: Paper on "Nonlocal-Cam" Published in eLight

Congratulations to Sathwik Bharadwaj and our former group members on the publication of their groundbreaking paper in the high-impact journal eLight!

The paper, titled "Exploiting universal nonlocal dispersion in optically active materials for spectro-polarimetric computational imaging," introduces a new kind of camera called the "Nonlocal-Cam." Unlike traditional cameras that only capture intensity, this new device is designed to see the "spectral texture of polarization," which is a unique property of light that has been previously unavailable for imaging.

The team achieved this by leveraging a phenomenon called nonlocal dispersion, which is the super-dispersive property of light interacting with certain optically active crystals. They found a way to use this effect to de-multiplex spectral information, which is a new and highly effective alternative to conventional methods.

The Nonlocal-Cam works by sampling polarized spectral states and using computational algorithms to reconstruct the full spectral image. This work merges the fields of nonlocal electrodynamics and computational imaging, opening up exciting possibilities for a wide range of applications, including biological microscopy, physics-driven machine vision, and remote sensing.

This publication is a testament to the team's exceptional, collaborative, and forward-thinking research. We are proud of this significant contribution to the field of optics and photonics.
