High-resolution imaging through turbid media is a fundamental challenge of optical sciences that has attracted a lot of attention in recent years for its wide range of potential applications. Here, we demonstrate that the resolution of imaging systems looking behind a highly scattering medium can be improved below the diffraction-limit. To achieve this, we demonstrate a novel microscopy technique enabled by the optical memory effect that uses a deconvolution image processing and thus it does not require iterative focusing, scanning or phase retrieval procedures. We show that this newly established ability of direct imaging through turbid media provides fundamental and practical advantages such as three-dimensional refocusing and unambiguous object reconstruction.Imaging performances of traditional optical systems quickly degrade with increasing scattering 1,2 , so that in the diffusive regime only low resolution optical images can be obtained 3,4 . However, recently, novel strategies such as phase conjugation, scattering-matrix inversion, ultrasonic encoding or the so-called "memory effect" have revolutionized this field showing high resolution imaging and focusing behind turbid tissue up to several scattering lengths [5][6][7][8][9][10][11][12][13][14][15][16][17][18][19] . In many of these studies, the ability to image through turbid media is facilitated by additional information gathered on the scattering medium. For example, placing a "guide-star" in the object plane, iterative algorithms have been used to correct for the aberrations induced by the medium 10 ; or the scattered field has been recorded and reversed to focus or scan the light back onto the object plane 20,21 . Here, we use the fundamental principles of the memory effect to enable direct wide-field imaging through turbid media using deconvolution image processing and a single-shot of the scattered intensity pattern. This enabled us to achieve, through turbid media, many of the same powerful features of standard deconvolution microscopy such as improved resolution as well as three-dimensional refocusing.The memory-effect, first described in the 1980's, is a peculiar phenomenon observed when light propagates through a scattering medium 22,23 . Within a certain range of impinging angles, known as the memory-effect angular range, the seemingly-random speckle patterns observed after the scattering medium are highly correlated. Deconvolution processing is a well-established and widely used technique in astronomy 24 , microscopy 25 as well as non-optical imaging 26 . It relies on the linear properties of imaging systems for which the imperfect image recorded by an instrument can be written as the convolution of the perfect object function with the point spread function (PSF) of the optical system, i.e. its response to a point source. Measuring or estimating the PSF of the system, one can restore, i.e. deconvolve, a high quality image from the measured one 27,28 . The deconvolution operation is known to yield better resolution than the diffraction limit...
