Abstract
Standard imaging systems provide a spatial resolution that is ultimately dictated by the numerical aperture. In biological tissues, the resolution degraded by scattering which limits the imaging at a depth. Here, we exploit the properties of speckle patterns embedded into a strongly scattering matrix to illuminate the sample at high spatial frequency content. Combining adaptive optics with a custom deconvolution algorithm, we obtain a resolution improvement of a factor < 2.5. Our Scattering Assisted Imaging (SAI, M. Leonetti et al., Sci. Rep. 9:4591 (2019)) provides an effective solution to increase the resolution when long working distance optics are needed.
