Wide-field depth-resolved imaging through scattering media has been a longstanding problem in recent years. In thispaper, we proposed a reference-less compact imaging physical model, where the 3D light field data embedded in thevolumetric speckle stack through a strong diffuser is explored and analyzed. By utilizing wave-optics and a coherentround-trip field estimation method, the scattering matrix of the diffuser is precisely calibrated as a priori knowledge.After then, the multi-slice targets are placed between the light source and the diffuser, and a set of defocused intensitypattern are recorded for recovering the scattered object field. The real object field is extracted from inverse diffracting ofthe field employing the conjugation of the calibrated scattering matrix. Wide-field imaging is verified experimentally byrecording a resolution chart hidden behind a ground glass. The technique shows great potential in lens-less wave-frontsensing and non-reference 3D imaging.
