An all-optical technique enables instantaneous single-shot demodulation of images at high frequency
S. Panigrahi, J. Fade, et al.
Transforming the landscape of optical signal processing, this innovative snapshot quadrature demodulation imaging technique effortlessly estimates amplitude and phase from a single acquisition—no synchronization needed! Developed by Swapnesh Panigrahi, Julien Fade, Romain Agaisse, Hema Ramachandran, and Mehdi Alouini, this all-optical approach unlocks high-frequency demodulation with impressive spatial resolution and continuous frequency selectivity.
