All-optical, computation-free time-multiplexing super-resolved imaging based on speckle illumination

Opt Lett. 2025 Jan 15;50(2):566-569. doi: 10.1364/OL.540701.

Abstract

The time-multiplexing super-resolution concept requires post-processing for extracting the super-resolved image. Moreover, to perform the post-processing image restoration, one needs to know the exact high-resolution encoding pattern. Both of these limiting conditions are overcome by the method and experiment reported in this letter.
