Imaging through a scattering medium is challenging but important for different applications. Most advances rely on computational image reconstruction from scattering signals. In these conventional investigations, speckles were always treated as scrambled grainy patterns. Directly seeing through scattering diffusers has never been realized. Here, a new strategy to see through random diffusers directly using self-imaging of speckles is proposed. By analyzing the physics, a direct observation strategy through scattering media is reported with improved image quality.
