Abstract

This study presents a novel all-optical method for super-resolved (SR) imaging using time-multiplexing with speckle illumination. Unlike conventional techniques requiring post-processing, our approach generates a SR image in an all-optical computation-free manner by interfering the object’s image with speckle illumination and averaging multiple speckle pattern images. Moreover, the method utilizes a single wavelength and requires no a-priori knowledge of the illuminating patterns. This advancement offers a simpler, faster approach to achieving SR in optical microscopy, with its computation-free operation making it particularly suitable for near real-time applications.
